Ummmmm- - - - -you do realize that's not a 235 balancer, don't you? It's one for a 250, which has probably been modified to fit a 235 by shortening the snout a little. Those are actually available brand new, for pretty reasonable prices. I'm not too fond of doing it that way because the rubber isolator carries the load of driving the belts. I make a brand new balancer, using a 6" diameter balancer for a small blockV8 and an inverted 2-sheave pulley off a big block V8. The pulley bolts to the inside piece, and overlaps the balance ring, which carries no load. It's necessary to do a little machining, but the end result works well, according to a few bolters who are using them.
