One tag is the VIN, one gives me "7465B" on one line, then  "27 75 .."


Before the "27" will be a 3. it's a 3.27 ratio... 75 means 7.5" ring gear...

1WLD BRD has L08 and 88 on his... 3L08 is A TL 3.08 88 is a 8.8"

All this info IS in the shop manuals... You guys that have 'em should read a little more...

Wait, what? It's a 3.27 open 7.5 instead of a 2.73 trac-loc? WTF?

Wow Michael, you're 0 for 4. No traction lock, no 8.8, no 10", no 2.73. Need more exposure to non-TC's! At least it IS a Ford rearend. Back down here now, after finding that my lugnut key was left here, the entire thing was pointless. At least I now know not to pull my rearend and try the gears since they don't match. Going on to live with the howl. No hard feelings though, I'm sure we can get something worked out - just a weird innocent mistake. I need to keep in mind you're still only my age, there's much more to learn about these cars, for the both of us.

On a side note, its time to look for a motor. One of the rings is near shot, getting slight oil burning - only noticeable when I manually shift from 3rd to OD on the highway. Fun. I'm thinking about just finding a crunched up TC in Seattle to tow back and steal all the good parts from over a long weekend.

The rest of the numbers were unreadable after cleaning them up. I didn't see anything before the 27, but yeah, 327 would make sense. Kinda sucks though, having expected to get a decent rearend in the car, only to have nothing get done since its no better than whats on the car already (with exception of gears that do appear to have half the wear as mine).

I saw that post of yours before, but those both should be running - I'd take a damaged car to strip of the rear, brakes, suspension.

My rear's fine, just noisy as hell (always has been, since '92 when it came into the family)...the main reason for the rear swap. I figure I may as well do it right though, with an 8.8. Would prefer lower gears for economy purposes (I got 34.5mpg on the drive up to Seattle yesterday!), but would use a 3.55 or 3.73 since most driving IS NOT at highway speeds. This was going to be a trouble free 8.8 swap, with very little needing to be done with the brakes since they were still drum, but no part of it came together. I can wait until I find a damaged TC to steal from if need be.

I've been more worried about the old 302 that was never taken care of prior to my ownership (at 160k miles) so its showing its age at 213,700 now. Emissions again in 5 months and I figure I may as well put the money towards a new motor instead of to a repair place to get my waiver (again, and what they did didn't change a thing - "bad" EGR. I wanted them to replace the seized o2 sensors but nooooo).

If the tag has the correct info, I'd bet it was swapped early in life...

Had a '70 Caprice with a 400 small block(or so we thought)... Every thing was correct, 2bbl carb, air cleaner, etc... Absolutely  looked original, till we checked the code stamped into the block... Was a TRUCK 350...

ah, the joys of workin with used cars!
ive bought, sold, traded, and given away alot of parts off used junk. i learned a while back that you always hafta get to takin stuff apart before you will every KNOW exactly what youve got.
there is no way to know the full history of a used car. especially sumthin that is 20+ years old.

in this case, simply pullin the wheels or crawlin underneath to look at the tag woulda been enough to warrant further diggin to find out exactly what was there before tryin to sell it.

live and learn, eh? :hick:
gumby - beauty may fade, but stupid is forever!

1st non-TC I've ever stripped. I'm guessing the rear was swapped before the original sale, because none of the receipt records I have mention rear axle. I have to be really careful on the rest of this thing...
