Does anyone know what years the F350s had 4" blocks in the rear? I'm pretty sure that I read somewhere that F250s used 2" blocks, and 350s used 4". I'm most concerned with I want to swap a 10.25 rear into my '91 bronco, and retain the factory blocks, if there is a such thing.
If they did use blocks from the factory, does anyone think this would be an over-the-counter part at a ford dealership, or wrecking yard only find?
Thanx
