Group,
This is what we are trying to do............This is junk O-540 crankcase with the "Vans" RV10 mount ring bolted to the top mount "Ears" and a RX8 Renesis front
cover and waterpump in proper position of the O-540 crankshaft shaft to see if the Mazda 13B / 20B will fit in the confines of the mount ring............The alternator
mount on top of the Renesis cover has been removed and alternator will have to be relocated............Hope the photo is small enough to send to the forum..........
Best
Kelly Troyer
