Need some input and opinions.
I have a 1972 1 ton with a 4 speed and am wanting to convert to TH400 automatic that came out of a 1969 C10.
My question is
Are the 1/2 and 3/4 auto transmission cross members the same and interchangeable to use on a 1 ton frame.
Heehawracing has some spacer brackets on parts board that came off a 1 ton Longhorn and I am wanting to know if this will work with my 1/2 ton cross member?
Thanks for your input
Ron
