I have 1949 F4, 226 Flathead. Rather than rebuilding the 59T 7006 4 speed crash box, I thought of installing a T18 synchronized.Any insights of pros and cons on how this will work?

 

I don't know about the T18. The T98 was available as an option in the F-6s. The early T98s (before 1953) can be made to fit. I don't know if the rear bearing retainer / rear motor mount from an early T98 will fit a T18. Good luck on finding an early T98, they are rare. I know, I've been looking for one.

Chuck at Chuck's Trucks is probably your most knowledgeable person for this question: Chucks Trucks LLC., Chuck's Trucks, Chucks Trucks

 

Thanks for the input. I have already ruled out the T18, it would take a large adapter plate and a few other details I think would take away from the truck itself. I will contact, Chuck Trucks.
