Hey Guys, That confirms what I thought. I appreciate the confidence Atomarc. No I have not made a gasket from "scratch" before. The gear box has both sector and tensioning adjustments. As with so many things with this truck it forces me to think, and improvise. I love that. Not to brag, but at work they call me Mcgyver. Because if I need some tool or device I try to make it first, rather than buying what I need. (not that it always works like Mcgyver)Once again you guys are the best.
