I am putting my original 260 back together after it came back from the machine shop and I am struggling a little bit with the two-piece rear main seal that came with my FelPro gasket set. The instructions say to insert one half of the seal into the block with about 3/8" sticking up on one side. This should result in the other side being about 3/8" below the edge of the block. The other half goes into the rear main cap with the same offset so that it mates up with the half that is in the block.<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal align=right style='text-align:right'>My problem is that the two halves of the seal seem to be too long. If I insert one half so that 3/8" is sticking up on side it is only about .2" down on the other side. So I can't get the rear main cap to seat correctly. Is it common to have to trim the two halves so that they will mate correctly? Or should I just go buy another seal and hope it works better? (Thankfully I live just a few miles from a Summit Racing warehouse)<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Thanks,<o:p></o:p></p></div><div><p class=MsoNormal>Joe Brown<o:p></o:p></p></div></div></div></body></html>
