9 inch install in 65 fastback

Well I finished my 9inch install into my 65 fastback...thanks to Steve (ultrastang) as I had read on his site
A few years ago that a 57 ford passenger car rear would fit...kept in back of my head and saw a housing
On cl here in nw Arkansas for 100.00. Then found a traction loc pumpkin for 300.00 with 3:50 gears..
Welded on Calvert racing spring perches....a nice big race car style fill plug and had to shorten
Driveshaft another 3/4 inch and presto!

An interesting experience...the third member had sat for unknown amount of time....I test drove today
And the rear would barely allow a turn or back up...I used Lucas synthetic gear lube says no additive
Needed....hmmmm....locker worked great in a straight line however corners another issue rear was nearly frozen I added the limited slip additive after a few miles and a few  burnouts and all is well. I'm guessing if a locker rear sits for a long time out of fluid the
Clutch discs get bound up (rust, corrosion?) ....anyway...regardless of what the gear oil says use
A modifier....easiest upgrade I ever did....detailed to the max......

Soiunds like you got your U-Joint problem straightened out, and got a nice 9 under your Stang.  Good job.

Re: 9 inch install in 65 fastback

Yeah....the fix for the ujoint is there is no fix in terms of a u joint alone it  is an 1100 series in my early 65 fastback v8 2v car....so fix is to cut off the driveshaft yoke at rear and install a 1310 series....then use a combo 1310/1330 joint....a 1330 series rear yoke won't fit the diameter of my early driveshaft....the shortening, yoke and balancing was only 85.00.
