Jim,
Glad to "officially" be here
Rubes -- That '84 is a good candidate for a swap -- especially if it has the 4.10 rear in it (84 only)!!!
Here are a few more pics of the frame buildup. It probably wasn't the best plan, but I built a chassis table for this project, fixtured up the old frame, then built something comparable out of 2x3 and 2x4 steel tube. Once I found out that there would be a few, ahem, limitations to grafting on a new front suspension, had to remove the frame from the firewall forward and graft on more tube to support the custom C4 crossmember.
Note that the frame components to support the diff and the front suspension are placed/tacked as of today. Still measuring/fitting and making sure things are perfect before I weld everything into place.
Note -- the 3rd pic attached here is about all of the oldoriginal frame that I might use on the new frame -- that is the backbone section.
