Sad Story On a Gear Vendors OD

Bummer alright...BUT have you delved into the unit & checked out the Damage ?? The gods smiling, IF spares are avail you still might come partially right side up - find an old mechanic who used to work on school buses or GMC's used to 2 speed units if you aren't confident.
The Van could've got rear-ended in o.d. & just lunched the cluster.. Delve deeper, if you haven't already & luck may be on your side...
Don't tell me ? Feebay/Craigslist/swapmeet ?
Logic says the O.D. trans but sealing this far.
Just my thoughts.
Don't ya hate it when that happens ?.

I think we all make gambles with 40+ year old car performance upgrades. And sometimes you roll craps! The Hot Rod gods can be fickle at times.
