well, my friend purchased a wrecked 87 gt for some parts and has the rear left over - what's it gonna take to adapt it to my 67? i know it's about 1/2 wider (big whoop) but the driveshaft length shouldb e the same right? and i'd have to mod the spring perches correct? any sites with info on it or a write up?

why waste the effort..find a 9 inch and it'll bolt right up and be stronger

And heavier. And possibly not the right width.

I have a fox 8.8 sitting at a friend's place waiting for me to build it. The width is perfect for 67-78. You'll need to dig up some ranger axles and get the spring mounts changed, but it's not that big a deal. A good driveline shop should be able to do it for you and get the pinion angle correct.

I'll post the donor vehicles you can steal parts (axles and brakes) from later tonight when I get home.

with the proper research the right one can be sourced.....just gotta know where to source one from..besides I build my motors powerful enough that the little extra weight of a nine inch is of no concern

Doesn't matter that much in a straight line but if you plan on turning the car (I'm more of a road course kind of guy), all that extra weight in the *** end doesn't help. And it's pretty hard to break an 8.8 with anaturally aspirated289/302 (even a stroker). If you can get your hands on one for really cheap (or free), I'd consider it a good deal. The only real downside I see with an 8.8 is that it's not a removable carrier design, which can suck if you want to change the gears down the road.

Axles:
Twod-side side axles from an 83-92 Ranger/Bronco II with a 4cyl or 3.0 V6 and7.5" rear, or two p-side axles from an 86-97 Aerostar.

Brake drumscan come from any of the same vehicles.

A 9 inch is stronger then a 8.8 that 8.8 might fit with some work cuting off all the mounts and welding on the spring perchs id like the rest of them get a 9 inch.

gotchaI'm more of a straight line guy......I love my removable carrier in my 66.....makes a gear swap a breeze..If I'm quick less than a hour

I really need to learn how to change R&P's, its something i've always said i would do, i've built motors, trannys, done everything else, maybe someone can make it a sticky? hint hint....

I did, broke the spider gears with bone stock 5.0! Had stock rims and tires (no slicks). It did take a lot of abuse before it broke however...
