housing end studs..where?

mbaird - the bolts from the factory have a splined shoulder under the head to assure that they don't spin and to be sure that they are precisely located. The heads are probably bigger than those on the Allen bolts you got and therefore distribute the stress on the housing end more broadly. I'd take those bolts back where you got them and get the correct stuff - is it really worth it to save a few bucks???
