Actually, worst case is like what happened to me - my transmission tail shaft snapped in two when the 7-1/4 failed and locked up, and made having to replace the rear end costing me a new transmission as well. That was an expensive lesson learned. Worst part was, I had a good 8-3/4" with 3.23 sure grip laying around but was too lazy to change the rear when i changed the engine from the tired 318 to the nicely built 360 with T/A heads.
Ok. Best case, when your 7 1/4 finally gives up, you'll be forced to install an 8 3/4.
Worst case, anything beyond best case.
To me, simple economics dictates doing the swap ASAP. Besides the potential overrunning clutch / output shaft / extension housing tranny costs, there's this simple fact:
A serviceable 7-1/4" has some valve, even if only as trade bait. A blown up one is just scrap iron, to be melted into more Hyundais and Prisus'.
No bucks for an 8-3/4"? Find an 8-1/4" the right width (Dakota? Cherokee?)
