So BTF is doing the work now, not G-machine? I'd love to see a built thread posted up so we can follow. Or on dezertrangers where there are tons of build threads.
But shouldn't you have the front and rear done together? I mean, if the front is done and the rear is stock, that will prevent you from being able to truly test the capabilities of the new front end. And it would be so sick to have long travel IRS, 3 and 4 link straight axles have been done plenty before. The way i'm imagining it too, with IRS you would have a better chance of keeping the rear seats than if it was linked. You would have the coilovers come up behind the seats.
Either way, this type of project has been a long time coming, i'm glad to see someone's finally taking these trucks to the next step. I just hope this project gets completed, it's a huge undertaking.
