Where can you buy a speedometer adapter? The car had a T-56 but was converted to a TH400 and now the speedo doesnt work.

I think Speed inc. has them but I'm not sure what to buy. A picture of the part would help to. Any info???

Heres there page, the th400 conversion parts are at the bottom.

Did you look at the TH400 FAQ on this forum:

... and looked at this post:

Thanks, I figured it would be easier to ask one of you than scan through 500 pages of info.

 

Yank sells a kit to switch it over. I've got one on my TH400.
Comes with a new ring to go on the out put shaft and a new magnetic pick-up.
