Meanwhile I was pricing getting the bed soda blasted, top and bottom with line-x covering top and underneath, wheel wells, etc.. Will need to save a little to get that done so I decided to attack the sides of the bed and its imperfections. Along where the trim was, water gathered and created pitting and rust. Nothing too bad but definitiely need some TLC. Wire wheeled that out. Took rails off top and fixed a few dents, filled in the seemingly random extra holes (PO mst have drilled since this bed is from my donor truck). Then topped it all with a fresh coat of POR 15-silver. Will go back in there next weekend and use skim fill to level off the pitted areas. Unless someone has other ideas? Here is a shot of the one side I worked on today. WIll get after the other side later. Looks kinda goofy now but it is a work in progress.
Hope to get pros to line body panels, fine tune my sad efforts at body work and professionally paint. THat will be a while since that will cost $$ 
Til then she will be a little rough around the edges. 
and in fact, put the originial back in the passeneger dooe since the LMC relacement just did not want to fit. 
It was a tad frustrating but the anti rattle kit and regular window seals were very easy to install. Also got a 302 sticker for the air cleaner to make the engine look a bit prettier. 
Then will take to get bed sandblasted and topped with some line-x..... replaced the fuel gauge sending unit nad now can tell how much gas is in the truck! 
Plan to use this periodically to tow the Miata to and from the track!!! 
Will continue the build thread though.
