So I've decided that the best thing for the frame rails is to take some scrap metal and cut it to size, then screw it using drywall screws to the frame rails, that way it'll be stiff enough for the hemi i'm installing....
Actually I've thought about just buying a new cross member, so i'll start checking that out with AMD and see what it would take. Looks like a solid chunk of work, but necessary.
Until further work on the crossmember and floorpan, I took the driver's door off, realized my lower door hinge needs to be new or rebuilt cause the lower hole is out of round, took my front grill out, took the driver's fender off (first time it's been off the car), and did some rust recon. At this point in the build, i'm both extremely excited to be getting on a roll with daily work on the car and i'm diving in far enough that I feel like i'm opening can after can of worms. Stuff is so easy coming off and since I know it's slower and tougher going back on, it seems daunting. I think the key to getting through it for me is just going to be daily progress, so I look forward to posting on this forum to keep my motivation up!
