Excellent now to figure out the pinion diameter and spline count. By the way my intent is to figure out if an r200 companion flange can be mated to an h190. The r200 spline diameter is about 27 to 29mm hard to say I lack a caliper at the moment and spline count is 27 grooves. What ive found so far is the h190 runs a 45mm shaft through the seal and the r200 is a 40mm that can be adjusted with a sleeve. By the way thanks Ron for the quick reply.
