Guys, I am attempting a 44 tooth speedo gear change in my SX. I know from the manual that all 1970 TH 400's have an 18 tooth drive gear. I need a 44 tooth driven gear. My housing reads 36,37,38,39. Everyone seems to call this a housing. The shop manual refers to is as a sleeve. What is the difference in the two options for this part? Is the sleeve the same as the housing everyone is calling it. If I get the 40's housing and the correct gear, is that all I need?

Thanks as always

 

AFAIR, yes, you get the 40s housing and the correct 40s driven gear and it should go right in.
