Prop Shaft

You need to keep the coupler about a 1/16 or so off the v drive output housing, but the safety collar can be as close as you car to make it. It you don't want them to touch, fine. But I a couple thousands with a feeler gauge is all you need. Just don't let it touch the v drive housing or the shaft log seal. It will cook the seal in a heart beat.
Also. McMaster Carr sells SS two bolt safety collars that are only 1/2 wide if that helps.

thanks sounds good ill keep you posted think i found enough room to get the CE .625" safety collar in there
