TH350 to NP205 Adapter
I'm looking for a drawing or dimensions for the stock adapter for turbo350 to np205. I can't locate one online anywhere that has dimensions. I'm working on a swap and trying to get some stuff in the ball park before I start.
Basically just looking for two pieces of information (see the picture): 1) Is the base of the 205 adapter angled? It appears this way on the advance adapters part. 2)Also, what is the height of the adapter from the base to the center of the shaft? Thank you

Re: TH350 to NP205 Adapter
I have never seen an angled one on any of my trucks, I think I have an extra adapter, I will take measurements for you, pm me for info..I have sm465 's with 205's and turbo 400's with 205's in my trucks...but pretty sure i have a 350-205 adapter

Re: TH350 to NP205 Adapter
since that appears to be a technical drawing, and it has the 3.5" dimension on it, you could interpolate the measurement (but Eldo has provided it) and you could measure the angle with a protractor directly on the drawing. Having said that, would make sure you got a drawing of the adapter for the correct year your sticking it into - if it shouldn't have an angle, then perhaps the drawing is for a 73 - diff frames, but still had the 205 for a year before the 203s came out. I think the 205s also remained in manual trans Ks for another few years beyond that as well. Anyway, just some thoughts.
Yella, welcome - might try posting a WTB ad in the parts section for what you're lookin for. |

Yella69, I may end up keeping the part for a future project. I might consider selling it in the future, but I won't be starting this project for a few months.
