Tulsa 6, Thanks for the info.Sorry to say I had to let the OD tranny go.
Before I met the dude that was sellin' it, I took every conceivable measurement I could think of off my saginaw 3 spd. Shifter mount location,Crossmember mount location,speedo cable hook-up,double checked length of case,length of input shaft.Then took my cast iron bell to compare it with the aluminum one that goes with the OD unit.
Long story short...You're exactly right.it would be very difficult to modify the exsisting bell to work with this tranny.Not that it couldn't be done,but in my modest(read,lack of expertise)opinion,it wouldn't be worth the aggrivation,and or,expense.
.Also,my original post on this subject indicated that this trans came out of a 4x4 P/U.I couldn't find a speedo cable hook up anywhere on the case.The guy told me it hooks up to the transfer case.
So that deal went down the tubes real quick.So,the search goes on....for now I would be happy to just find a plain ol' sag or muncie 4 spd.
A blessed Christmas to all,
