Question about supercharger and AC belt pulleys XJR6
I see two different parts listed by various vendors for the supercharger belt pulley:
Ribbed - EBC11527
Not Ribbed - EBC11528
Are they interchangeable? If not, is there a difference by year or?
The AC idler pulley is NBC5012AA, same as XJ6?

The idler pully has a common Gates # and avail at the locol auto parts store and is flat on the belt contact area
sometimes the idle pully long adjustment bolt can be frozen so remove the whole pully bracket and work on the bench with some heat on the threaded block that runs up and down
The idle pully shaft bolt must have the nut loosened
There is a mod to change the size of the supercharger pully or the crankshaft pully to get more boost
I don't have the SC
