I got a 1st series '55 Chevy 3600, 8 lug, 3/4 ton truck. I'm in the process of swapping out the front end to 6 lug and will soon be moving on to the rear end. The '55 is an open drive shaft. Do any of you know what 6 lug rear differential years with open drive shaft I can use on my '55?? Thank you all again!!

I would look for a '67 -'70 half ton truck rearend. They are 12 bolt with the correct 6 lugs and the width is very close to correct.

I used a 65-66 truck rear end on my 46, not to wide, lots of available ratios!


It's easier to get forgiveness than permission!

Thanks JiMerit Boltr#43 and 52Carl. I'm very new with this driveline topic. If I end up getting a rear end from a '60s truck with the correct width do I have to worry about swapping out my transmission because of the gear ratio? I currently have the stock 235 engine and tranny. I assume the gear ratio from a later truck differential will be different than the the 4.56 gear ratio that came stock with my 3600. Also can I use my current drive shaft? Thank you very much for imparting your knowledge on this topic!

You might be able to use your current drive shaft. GM is famous for continuity throughout many years of production.

Ok got it 52Carl I'll let you know what I end up using..crossing my fingers the drive shaft will work with the new rear end. I'm glad I'm not restricted to the '55 1st series.

Shouldn't be an issue with the driveshaft. Worst case, it might need to be lengthened or shortened. If it's just a u-joint fit issue, u-joints with different size cups are available at any good driveline shop.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

Klhansen thanks for your input. Do you know if I have to worry about a transmission swap since the gear ratio will most likely be different?

Unless you're looking at an overdrive transmission, it won't make a difference. Most transmissions are direct drive in top gear.
Your rear axle ratio is 4.57 which is pretty low. Later axles are likely a higher ratio (eg.4.10, or even higher) which would help keep your highway cruising engine RPM down. Unless you're pulling stumps, you don't need a 4.57 rear axle ratio, although you could find an overdrive transmission, which would allow you to use a higher numerical ratio axle and still cruise down the highway at comfortable engine RPM's.
