Hey guys! I found a 32 spline SM465 / 205 combo for 50 bucks. 205 needs a new front seal, and the SM465 needs new o-rings, and for the piviot ball on the shifter to be re-welded to the shaft. So, I've decided I'll run my truck married until I find a good 2wd NV4500, at which point I'll run the divorced 205. My question relates to my cab though. As it stands, my cab has a low hump (originally a 2wd with a TH400) floor in it that doesn't come off. How would a guy go about cutting that out, and installing a new removeable high hump for the SM465? Should I just cut out as much as I need, then run bolts through the floor, with some silicone between the two peices, or should I cut the entire section of floor out, and weld in a new peice with the bolt holes in it?
