Gale,
This is what I did and it worked out well for me, I think it took me about 10-15 to get in using a platform jack.It supported the frame nicely with a help of a few blocks to balance of the weight . I think Harbor Freight sells them or something fairly similar. In any case it worked like a charm and was also used with the front frame as well.
As for the finish on the frame, I tried to get a color close to the factory original. Mine was a olive /greyish color, The powder coating I used it is fairly close IMO but not exact, then again I was not hung up on the matching it as much as I was looking for something other than black, but I digress. Another personal choice for my project.
