the "thin" balancer,which is what i had before the stroke, is .950" thick, the pos prw is an ample 1.185" thick. the snout lengths are the samebut you cannot seat the balancer on the crank timing gear because the back of the balancer body hits the timing mark area on the cover. If you could be so kind as to measure your balancer for thickness , I'd really appreciate it. in search of sfi rated balancer .950" thick. Thanks, Mike
