1947 chevy car rear axle

Hi I have a 1947 Chevy Stylemaster. I am putting in a SBC and Automatic transmission. I would like to know if the rear axle in the car will work or if there is some sort of conversion for it, or do I need to get a new axle and driveshaft.

Thanks for your help

I've got a '48 Fleetline...and the short answer is no. The design of the rear axle prohibits any adapting strictly at the transmission.

That's not to say that you can't make it work, but without changing the mounting of the rear axle to the leaf spring, there's nothing keeping the axle from wrapping up on the pivot. You're probably looking at swapping out leaf springs and shackles, removing the factory leaf spring pivot bracketry, and adding conventional leaf spring mounts with u-bolts. Unless you've got some really good reason to reinvent the wheel, it'll probably be easier and faster to simply change the entire rear axle and leaf springs out for something more conventional if your plan is to change the engine and transmission.

that 47 should be a torque tube rear axle setup.

Requires different trans , drive line , rear differential ...

the diff would need special locating mount to center the axle in the wheel well opening or replacement leaf springs with centered spring pin
Dont worry how old you are... it is the mileage on your body that adds up.

Thanks for the info

I was hoping I did not have to do an entire swap. But I had a feeling I would. Does anyone know any companies that make swap kits? Also what would be the best rear axle assembly to try to find.

Thanks for any help
