Underdrive Pulley

Tried to search this but I really can't come up with a definitive answer...

I have an SLP underdrive pulley that was bought for my LS2 GTO but it was never installed.

I now have an LS1 Trans Am and I will be changing my cam soon. Will the LS2 UDP work with the f body LS1? It looks like slightly different part numbers but the one for the GTO works for LS1 or LS2.

Thanks

Thanks.... I guess my wording in the original post is confusing. I'm asking if that pulley, which works for ls1 and ls2 GTOs, will work with an LS1 F body.

I'm just curious if anyone has actually tried. I guess I'll be the guinea pig. Most other UDPs I find work with GTOs and F bodys.

I asked SLP this question a few months ago. They are the same pulley. I asked because I didn't know which one to buy for my engine...I'm running F-body accessories on my GTO LS1 crate engine.
