OK how did you accomplish this???? Curious.

Paid a diff specialist.
Had no intention of doing it myself.

still significantly cheaper then trying to get a set of axles shipped to AU.

Tom, yes I am interested in the rotors that you used. I am thinking you must have used a larger diameter rotor than the stock TC and therefore you had to modifiy the mounting bracket. Is that correct?

Bump.

If anyone is interested in keeping the 4 lugs and upgrading to 31 spline, this is a great deal on ebay. It is what caused me to start the thread. I'm not gonna go the drilled axle route. Just to risky for my taste.

They came out of a Turbo Coupe. I verified with a question to the seller. The ad description also states same.

That's cool

I buy a lot of parts and hate when people get jacked up or wrong stuff

Is it the smartest thing to do, no. Does it happen everyday, yes. Hang out at a tire shop for an afternoon and see how many people have been driving around for thousands of miles with a busted off lug. I consider that to be more dangerous then a welded axle with the bolt pattern re drilled.

Just curious how does someone find the exact drill points without an indexer. Having a missing bolt is no where the same as drilling a hub by hand. Not to mention the fact that what will a person use to INDEX the drill points. This is one of those things better off not dun. I have the ability and the machines to index the drill the s and i would never attempt it. Just me i am nuts any way!!

I want to say that http://www.brakesrus.com has five lug rotors for the TC rear but their site is down right now. They are solid rotors and I believe a little cheaper than the ones Tom posted.

As usual Tom has all the goodies!

Not really Darren i am just old. And old folks just have been here longer to get more GOODIES. Don't worry you will catch up when you are my age. From the photos of your cars they are looking like real GOODIES TO ME. Cool cars. Thanks have a good day

By the way i like the BLACK ONE VERY MUCH. Just saying!!

Quick question Tom, will the rear rotors for the Mark VII that you posted fit an 87-88 TC rear end or are you having to modify the way the calipers bolt on to make them work? I pretty sure that is what you are doing but not 100% sure.

The hat depth is different. Unless you make new caliper mounts, they won't work.
That's why I said there is NO stock Ford 5 lug vented rotor that will work with a TC rear without mods.

Guess I'll leave the tech up to the old timers who have seen it all, done it all, because someone like me who has spent hours in junkyards and parts stores measuring and comparing parts doesn't know shag-all.

By god if i posted a pic of a mod, I'd be sure to tell everyone how and what I did to accomplish it. I guess that's because i can remember a time when everyone here helped one another, and weren't all ego braggarts...

I missed what you said on the first page as you guys were talking differentials so I skipped over it...pays to read all the instructions before assembly!

On another note, there is a guy here in the Houston area who is a friggin' wiz at brake conversion and building the brackets to make them work. It helps that he is an engineer so he understands the geometry and he does all his work in CAD so its money and super clean looking when its all done. He also builds T-5 and builds the AODs with the new auto tranny guts (sorry not an auto guy so I cannot remember which one the guts come out of) and to top it off he is a nice guy and charges way to little for what he does. If anyone would be interested in a kit that would convert a TC rear end over to the Mark VII rotors using SN95 axles and reusing the TC calipers and pads let me know and I can get you his contact info. Anyhow, just thought I would throw it out there. Here is one of the threads on a local Houston Mustang site and you can see some of his work and the CAD renderings:

http://www.westsidemustangs.com/thread74926.html

Hopefully you can see the thread if you are not a member. I talked to him a little while ago and he is interested in working up a model of this and seeing what it would take to do the adapter brackets. The model he already has is for the Fox length axles so he does not think it would take to much effort. I will post this in another thread and link it here if anyone is interested. It may take a few days as he does have a day job and other hobbies.

Darren as you know by now i make things work. By the way the axles i used in this conversion are not 30" as the stock TC 4 lug units. So basically everything i do is custom. That is why this old guy with no experience has a big following with local HOT RODDERS. They pay me for my ability to make things work. If this makes me a know it all old guy so be it. Yes those rotors are 10.92 LSC Lincoln And if memory serves me the stock setup works on a 30" axle. But if it does not i make it work. That is what it is all about. Just me an old know it all old GUY with a welder and some ideas i my head. Thanks

In my 87 Cougar, I used Moser axles with c-clip eliminators which did not allow me to use disc brakes. So I am using the factory 10 inch backing plates and some 5 lug hardware from a Lincon Town Car. I recommend that you save up the extra 100 dollars and use the SN95 Axles because they are only 259 per pair on Summit Racing. That way you are sure the ends are square and not brittle from excess heat. the come machined for c-clips but can be used with the eliminators. Word of advice if you do the eliminators, make sure you take it to a shop that does custom work so that they can trim the axle to length otherwise the hub stick out a little wider than before making tire fitment a concern and on drums the gap between the backing plate and the drum without tpuppies was 1/4 inch.

According to the Cool Cats website, another possibility for using the stock calipers on a TC rear with a 5 lug upgrade is to use the 1990 Mazda MPV front rotors with a 1/8 in spacer behind them. Has anyone here done that swap?
http://www.coolcats.net/modifying/4to5lug.html
"Or, you could do the ol' Mustang conversion trick: use 1990 Mazda MPV (V6, 3.0) front rotors, and 1/8" spacers. Place the spacers between the rotor hat and axle to put the rotor back into alignment with the stock Turbo Coupe caliper location."

The same site also claims you can use the rear 10 discs which came on the 91 - 92 Mark VII.
"From 1991-92 the Mark VII had 10" vented rear discs in 5-lug and those would be the ones to get. You could then reuse the other stock Turbo Coupe components"
