Well getting the new frame rails in is a little time consuming, but at least one is mounted for final placement, and welding prep. Next will be to knock out the old frame section that will not be used. Looks like at least a solid 1 1/2"maybe up to 2" more inner tire clearance, I did not get a chance to measure it that well yet, there are some tapers involved. I also ordered a 15 gallon SS tank from Rick's tanks that is narrowed, and lengthened, with a sump. Just a bit on the pricey side, but what are you gonna do to get past the inspectors?
