I found 2 part #'s LS-1: #12557075 and LS-6: #12557752.

I have a 98 LS-1 and I'm going to use a ported LS-6 oil pump from TSP. Which part # do I need??????

Thanks

I was in this same situation when i installed my oil pump on my 98 recently. I used the new ls6 one its thicker then the ls1 one but it seems to be just a tad bit looser the ls1 one. The old one felt more tighter. Luckly i repalced it I ended up doing the install once with the old Seal and found a new one and decided to do it again. I inspected the old seal very carfully and there seem to be a small cut in the old seal so it was a good thing i changed it out.
