I had a lot of difficulty trying to find the $75 SST 09301-00110 to align the Damper Disc for mounting to the flywheel. Until I measured the shaft and splines and searched for it that way. 15/16 shaft x 21 splines x 15/32 spline height. (search: 15/16" X 21 X 15/32") I bought the PIONEER TAT5306, but now I see the M-PACT AT5306 is slightly cheaper. (Either way, less than $5, including shipping!) Just wanted to pass this info on!
