I used a 78-79 f-100 shift collar and around the same time shift lever since my old maverick shift lever would no longer fit. I had to do some minor fabrications but if anyone is interested in knowing how i did it, message me!
If you are up to it, a great way to share your experience is to write a Technical Article on the swap. http://mmb.maverick.to/forums/tech-articles.50/
That's a good idea @mercgt73. I had a really hard time finding the right shift collar for my '70 Maverick so I'm sure many people would find the article useful!
