Protrans pro brake 7.0 index

I now have three off these (powerglide)for my cars with different low gears in each one. A 1.69 for my heads up car,(big block) a 1.98 in my black Duster, and a for now spare with a 1.80 gear in it. 6 bolts to switch from big block to small block use. Zero safety shields needed. Takes least than 5 minutes to change bellhousings.
