Contact Steve at
http://www.industrialchassisinc.com/ about his crossmember for the TF trucks that runs Dodge Dakota pieces.
Ask him about running bags with it and being able to lay frame.
The crossmember for the TF trucks is 750 plus you need to find Dakota suspension and steering but it is well engineered. Best part is that you have no hassle getting your sheet metal to fit outside of a bit of inner fender trimming around the
A arms. No fabricating brackets for a radiator support, no fabricating bumper brackets,
If you are bent on a subframe swap the second generation Camaro is still one of the better ones as it is tried and proven and there are excellent instruction threads on the net Lux Blue did the go to thread on the HAMB a few years ago that gives great detailed instructions plus photos.
http://www.jalopyjournal.com/forum/t...ne-day.148978/ If you don't know about the Hamb it is a traditional hot rod and custom board that does not allow anything made after 1964 (65 with same body style like a Rivi) no billet wheels, no billet engine stuff an no LS or late engine discussion. No joining and then showing a photo of your ride rolling on 20's. I've been on it longer than I have been here but it isn't for everyone. Still read the thread to be able to fully understand that subframe swap.
I've got a Jag XJS front suspension that has been trimmed down and the spring buckets are cut out for bags but not finished and there are plates for bags for the lower A arms I drove down to Bend to get it but decided not to use it in the build I have going now. I decided not to use it now because it doesn't have coils or a sway bar with it.
The Crown Vic isn't that hard to put on a TF but the wheels set out wide on almost anything you put them on and the wheel choices are pretty limited if you want custom wheels that fit inside the fenders.
My personal opinion which isn't worth much is that "laying frame" is the goofiest automotive fad to ever come down the pike. Think about it for a minute. What is actually great about making your suspension look like is broken with the tops of the tires laying in several inches, and the truck looking like it has been abandoned for so long that it sank into the ground.
