My parts car came with what I believe is the cheapest version of the ACC carpet. It's very thin, kinda like mini golf carpet as mentioned above. I have a 94 and decided to use the black 93 SC carpet over the ACC and Mark VIII carpets I have. I can try to get pics of the quality of it if you guys...
I've got one I just swapped out. I just went out there and if you turn the bearing housing (part that clips on) about 1/4 turn clockwise it pops right off. I always swap to a Timken bearing instead of the cheap one that comes on the slave.
