The trany is most likely the ford f150 1984 -87, four gear is overdrive. The best info I seen is Secrets magazine 2006. Also on this forum is a gentleman by the name of Ken Parker, he is quite knowledgeable on this subject.

Ken Partker does a complete kit to include all needed to install the modified trans. Includes trans, shortened torque tube, driveshaft, radius rods and all brackets for clutch/brake pedals as well as e-brake handle bracket.
Excellent kit that has been installed in many Model A's.
I have Dave Delmue,s kit and I really like it . Drop in with no frame or brake cutting. Here is a post from old FB about this.
"There are three people that I know of that sell the conversion kit using the 84-87 Ford F150 truck OD transmission. The first is Gary Bernard in Ft. Worth, TX (817)624-1441. Don't know the cost of his kit but he is the only one of the three that uses the standard Model A bellhousing. This moves the transmission farther back and requires that the frame crossmember be notched and the brake cross shaft to be modified. Ken Parker in Van, TX (903)963-1650 sells his kit for around $2500.00 and he uses the shorter AA bellhousing as does Dave Delmue in Morgan Hill, CA (408)930-4502. Dave's kit is around $3000.00. All three sell a complete bolt in kit. I feel the shorter AA bellhousing makes for a better installation and less modifications to the car itself. All three have very good reputations.....AL in NY. "
I too have one of Dave's trans & like it and the fact that you needn't butcher anything. A bit pricey but a complete "kit" with like new trans & well engineered. If I had it to do over I think a taller 2nd gear would make it a bit better.
