I know of two sizes of dust boots, theres a shorty 1" boot or so and a longer 2.5" boot or so. I'm sure they are mated with the correct yoke. Not sure about the specifics about the differences. But originally these were and are street production cars.

I myself used the shorty boot to help achieve about 3/4 to 1/2" clearance from bottoming out the yoke. Ive been there with the wider clearances of the driveshaft wobble and actually loosing one. Was fortunate that I didn't catapult when I lost the loose clearance one.
