that may take some digging but do you have the rear were you can run a tape measure. If all works and the axles don't spline, you may have enough bolt flange to have the bolt pattern drilled. Just a thought ! !
But if your staying with 6 lug you can use anything up to `69 model year, complete axle assembly, you might have to do some trimming of extra metal from the axle housing and add springs pads to it, you can get the pads from summit for it...
As I have an automatic in it now, I am going to need everything to convert it to a manual. Thinking a T-5 should work just fine behind a stock 350CI.
Any stock T-5 items/parts that will just bolt in? Someone sell a kit? Figure that I might use a hydraulic master and slave rather than a stock type clutch linkage unless someone has a kit that will just bolt right in.
Although a standard 4 speed and stock Chevy/GMC parts would be fine. Was just thinking about it being nice to have an overdrive.
