We made it back from Montana, and I started disassembling the donor car before I even got it off the trailer. In spite of its appearance from the fire, the underside of the car is surprisingly solid. I'm excited to remove the parts I need, but I'm going to have to remove the scorched engine (another reason that plastic valve covers aren't a good idea) and the front suspension before I can get to the subframe. Unfortunately, I have a Dakota with leaking freeze plugs in the garage that's in line ahead of the Eagle project, but I just got the transmission out today, so if I can find some new (brass) freeze plugs tomorrow, I'll be able to put it back together and get it out of here.
I've already been able to salvage the door hinge mounting plates and bolts from the 1985 Eagle to replace the ones that broke on the SX/4, and I bet I'll be able to reuse a bunch of parts like that before I'm done. I haven't ordered the roll cage yet, but I think I should before I get too much farther into the fabrication so I can make sure the mounting plates will be in the proper places. I'm also wondering if it would make sense for me to cut the inner rocker panels out of the 1985 and shorten them for the SX/4. I'll have to see if that will be less work than having new ones made for the SX/4. I still have to swap the rear axle on the SVO Mustang, but I feel like the Eagle project is picking up a little speed again. I'll post more pictures as I get further into it. I also need to decide if it would be worth the trouble to swap the inner fenders from the 1985 to the SX/4 as well, but I think it will probably be easier to just patch up the thin spots.
