NP205 to 3053A trans adapter and bell housing
Post by calpyro on Jun 22, 2006, 9:58am
I just picked up two 3053a 5 speed transmissions yesterday at a Government Liquidations yard yesterday.
I got started tracking down the bell housing, adapter plate, flywheel, and starter at a big truck salvage yard and found out what I kind of already knew. The Bell housing that fits the 3053a is rare. However, with the help of the owner of the salvage yard, I came up with a solution to the bolt pattern problem. He found a common (very heavy steel) bell housing that can be modified (aka drilled) to match the pattern of the 3053a. The bell housing is the most common type for a 70's-80' big block Chevy. It has a machined surface in the areas that need to be drilled to accommodate the new bolt pattern. Today, I am going to get a sheet of clear Lexan to put over the transmission to acquire the bolt pattern and then transfer it to the bell housing for drilling. Problem one solved. I'll take some photos if I can figure out how to post them.
Additionally, I contacted a company that make adapters for transmissions to transfer cases and they are going to make an adapter to fit a NP 205 to the 3053a. On Monday, I am going to drive to their shop and drop off one the transmissions to use for the fabrication of the adapter. The company that is going to make the adapter has been interested in fabricating for the 3053a but did not have the time to acquire one for mock-up. When the adapter is figured out, the company is going to sell them. I will also give them the Lexan template for the bell housing for duplication. Hopefully, they can sell both the adapter plate and template as a kit for the 3053a.
