My P&G Model 300 Valve Gapper set-up arrived today, fairly complete seems in good condition BUT... Not the Outer Barrel & Base Adapter pieces that I was hoping for my Stovebolt 235. Needing a S Barrel Adapter, J or J-1 Base Adapters. EDIT; Found that the #30 Outer Barrel #360260 Marked 396/427 and the J9 Base Adapter look like they will work with the Isky springs on my #848 261 head... Still wanting a S Barrel Adapter and J or J-1 Base Adapters for the stock valve springs Please do contact me if you have the needed parts, I'm anxious to see if can get this gizzmo to work... Thanks Again, Dyno Dave 360-774 -6246 fine6inline @yahoo.com
