Mick, what length are your arms? i see how your lower mounting point is higher than mine by a couple inches.
Bob, the rack seems like it is going to line up ok. still trying to get the length of my arms right. I was going with 9.5" for the upper and 13" for the lower, I read that this was the original length somewhere around here, but that doesn't seem like it is going to work.
haven't put too much thought into the rear but I will probably go with something like alfy built:

I wanted to use the Ford IRS but it seems like I can't get rid of this Jag IRS so I might end up using it afterall.
