Thank you.

No problem Mickey. You know I enjoy researching the info and being able to help out when I can. BTW - Your original ID (Inner Diameter) you listed above of 1-1/4" is a tad off. The correct inner diameter for the seal is 1-1/2". Bolter rfs56trk is also 100% accurate that the seal "P/N 9613S" is correct for your application too. You can see that number cross references to the original GM# 3746212 (among many others) if you scroll down this finditparts.com part details page. They also provide detailed measurement specs for those interested in that level of detail. smile
