Hey clhaney
I am going to attempt the same thing except I want to get back into oval track cars...I would get a real trailer receiver (Reese type) and bolt or weld it to the frame. Suspension wise I think you will be ok...brake wise...upgrade everything...if you live in a quiet country area you might be able to get away with the stock braking...if you live where there is a traffic flow put newer more modern brakes on it....
I could never even imagine trying to wrestle an old truck like this with out some braking upgrades...back in the day yes...now 2015...not a chance..
My 2 cents for what is worth...
