Jim;I'm using my old, slow, back-up computer and it's timed out on my twice while trying to respond to you so I'll keep it short. Just curious, is your VR-58 unit a Direct Oil (DO) version plummed to crankcase oil? I had John Erb johnerb@sbcglobal.net modify my VS-57 unit into a short nose (SN-60) version and I'm working with Gord McMillen rexrep@telusplanet.net for the brackets, pulleys, belt, bonnet and lots of instructions. Both of those guys are really up on this stuff and can help you along. One major change I've made is that I will not be using the 2 piece blower pulley, but a one piece billet toothed pulley for the head unit and crank. There are many other changes I've mad and are making. Send me a PM or e-mail and I'll tell you more and send some pictures.
Good Luck,
Rono
