[ERA 778]

Adding to what Dan said, my ERA is #778, after the major upgrade. Bonding the body is not a difficult job at all. It's more straight forward than the method described in the manual (Bob, are your reading? The manual is out of date on this!) The biggest challenge is that you need several friends to help you twice during the process: to lift the body off the frame, and to drop it back on.

I had several things I wanted to do to the car myself that worked out much better by having the car completely disassembled. I painted the underside of the body and did some polishing on some of the aluminum panels. The pneumatic riveting tool from Harbor Freight is a MUST!

To me, doing the bonding was the right choice, plus it saved me some money that I could use elsewhere!

There's no bonding on the Unique car. It goes together more conventionally, I think.

One other comment> Take a look at the assembly manuals offered by both. There is a lot to be learned just by reading through both of them.

Good luck!
