Hello to the FTE group. I currently own a 57 COE used as a hauler for my Mickey Thompson 63 427 Lightweight Galaxie. I'd like to start with one easy question: is there any direct replacements rims to change out the OE Widow-makers currently on my truck? Living in SE Michigan there're still some truck tire shops that know how to replace tires on these dangerous. If out on the road a flat could present a problem.
I'm an Electrician Leader at the Ford Livonia Transmission plant that builds the 6-spd (6R80) for the Mustang, the F-150 and F250 trucks. The bigger transmission (6R140) is made in Sharonville, OH.
BTW, I'm new to this format, so please be gentle.

 

We're always gentle. And glad to have you hanging around. I'm gonna guess that your COE has the 6 lug x 8.75" bolt pattern. IIRC it's too new to have the 5 x 8" pattern. Whichever it is, tubeless replacements exist in both 22.5" and 19.5" sizes. Before going through all that it'd good to if you could clarify which bolt pattern you've got. Stu

 

You're right, from the photo below they're 6-bolt with 19.5" tires. They have the RH and LH threaded studs. Destroyed the LHs once, thought they were RH .

 

If yours are 19.5", they're already tubeless. Unless you've got a mixture of sizes. Stu

 

That thing is a Sweet truck
