Welcome, Looks to me like you have a nice clean start. The Pumashine Gusset kit is the way to go, not only that he has a lot of custom goodies for the R. I'm pretty sure there's some TX guys in here to that could help source a welder for you if your not installing yourself. If not, check for local Car builders that do chassis work.
And yes, you can not stay away from the R! I recently sold mine and going through the 12 steps of recovery now (1st step - find a frame and start building another).
