Joe, this looks really cool.

Sorry to hear about the rust, but really like the way you're thinking with the suspension.

That's similar to my train of thought, and of course there have been many before us with the same starting point.

At first I thought that the plates you mount the diff to might not be enough, however, they're really not bearing any vehicle weight, just the diff, so should be good.

Wishbones look like good geometry, I'm thinking to somehow get the coilover mount inside the lower A-arm. I know lots of cars have them outside, but it's a goofy hang-up of mine.

Did you have to cut up the tub at all to fit in the second row of rear lateral framing?

Really nice to see this. (thumbs up emoticon!)

Thanks Steve. Means a lot coming from you considering I have been studying your website and copying as best I could - your site made the transition to the 63 much easier - that's absolutely true. Yes, unfortunately it did require cutting into the cabin area but not as much as I first thought - but still hated doing it. Due to the placement of the springs, I had to cut just into the base of the rear deck by about an half inch. Springs could have probably fit on the inside of the lateral framework with professionally designed A arms. Honestly, I just went with what I thought I could do safely and with least cost.

I figured you may have had to, but it definitely looks close.

I've been thinking about cutting a swath out of that area, specifically the vertical part and moving it forward; of course I think that that part contributes much to strength so hopefully I could recreate that strength further forward. That would reduce the area available behind the seat, but make more room for the suspension. Could even cut a bit more out front and then weld that in below the gas tank, or just fab something similar. Just thinking out loud.

But if you just cut a bit off the corners and managed to sneak that new frame assembly in, that is simpler and likely stronger than I could do.

Keep it up Joe, looking forward to whatever you're willing to share.
