Any 9" bolt-in options for 85 turbobird?

just picked up an 85 (former) turbo coupe that I'd like to throw in a 9" since this is my new circle track car. ive searched through these pages with no avail, but are there any bolt-in 9" units for these chassis?

Nope, by '85 only 9" remaining were in E & F Series... No Fox chassis ever had a 9"... Stangs didn't get a 8.8" till '86 and Turbo Coupes in '87 & '88(these TC have 3.55 or 3.73 gears)... There are some '88 5.0 Bird/Coug that also have 8.8", but it's a grandma 3.08...

I'm familiar with the fox Mustangs, had a few in the past. Just trying to decide if i want to spend all the time and money into an 8.8, 6.0 ish gears, spool, c-clip eliminators, etc or find a 9" to fit, I've already got the center section from my other racecar that i could use.

Install two of the 8.8" 3.08 & you'll you'll have 6.16 gears... :rollin:

Could probably get away with single traction, one axle could pull right and other left... :hick:


You may know all this but possibly can find a 9" housing from early Stang, Torino, Cyclone etc that can be modded to fit... The '57-'59 full size fords actually have the shortest housing of any 9"(but I believe use small axle bearings, as did later small block versions)... All the full size had 9" thru '66, beginning 1967 into early '80s the 6cyl & 289/302/5.0 got anemic WER 8.5" rears(AFAIK parts non-existent), larger engines still used 9"... I believe all the Lincoln Versailles and Granada/Monarch with rear disc brake option used 9"... Drum brake versions used the py WER 8.5"... All Maverick/Comet from '71 used 8", the '70 used the 6¾ Falcon rear...

Considering how vast the selection of 8.8" parts are and that either a fox or sn-95 setup bolts right in place, of guess there really isn't much of a market for a bolt in 9".

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

I would bet you could get an aftermarket bolt in 9" housing for a Fox, but I'd also bet it wouldn't be cheap

I have the 8.8disk brakes on my other 9" But just measured, its like 6" wider than the 7.5 under the chicken now. Haha so much for that.

Gonna go junkyard crawling tomorrow to see if i can find anything narrow. I'm also throwing around the idea of 90s tbird IRS if it can be installed without too mush effort. My rulebook doesn't say i can't.. Just that it has to be factory for make and model. Thoughts?

The independent mach1? Sn-95 rear almost bolts in. Its expensive, but there was a guy on the smoking tire that dropped one in a 88 sport.

C-clip eliminators suck at best.  So why not just put 9" ends on an 8.8 housing and call it a day?  You are going to order axles anyway so this would eliminate the c-clips.  An SN95 Mustang 8.8 will bolt right into a Fox Bird and is the right width.

I'm actually taking a good look at this setup http://www.quickperformance.com/QP-1979-1993-Ford-MUSTANG-FOX-BODY-9-Inch-Housing-Axle-Package_p_4015.html

I've already got the 28spline lightweight spooled center section with 6.0 gears. I've already got the disk brakes.  Compared to buying a disk brake 8.8, finding gears and spool, 9" ends And new shafts, plus the labor to set up/weld in the ends, cost wise likely similar but if i want to switch gears in the future, 9' is the way to go
