I've got a 1962 Morris Minor 1000 2 door car about 15 feet from me... I dont see a S-10 fitting width or length.
It is a steel S-10 frame , so it can be cut n welded.
I bought a chassis kit from Jegs with roll cage for my Morris.. a straight axle will under the front, 4 link drag style suspension in the back end
Yesterday is history.
