That's probably good advice, Bill. But I just hate to mess with a new original arm especially since balancing was Thorp's claim to fame.
It's time to move on to the chassis and the body is still undecided.
I've got a new plan. Howie thinks the chassis most likely had a 3.9" wheelbase and a .9" guide lead. I'm going to build the chassis to that wheelbase. That will fit all the bodies shown below but the Mirage, so the Mirage is out of the mix once I start the chassis.
For the guide lead, I'll have to fit it to whichever body has the shortest nose.
I've added another possible body to the quoted post below. It's the Dynamic Lotus 40:
Here is a vintage butyrate plastic Dynamic Mirage.This one is now out of the running. The wheelbase is too long.
Vintage butyrate plastic Dynamic McLaren Mk 3:

I forgot to add another possibility so here's the TrueScale Lexan reproduction of the Dynamic Handling Body Lotus 40:
This is the later version of the Lola T70 that Dynamic introduced a month or so after the Arco Nats. The main difference from the rare first generation version is a slightly longer nose.
Howie, even if you haven't decided on a body yet, if you know of any of the bodies you definitely don't want to use, let me know.
Also if your were really considering the 4" wheelbase Mirage let me know that too and I'll put the brakes on the chassis build.
