I think much of the cost of the Kirkham "original" style suspension is getting the girling brakes and other traditional parts that are made out of "unobtainium". The Shelby CSX?000 cars use modern brakes with their tube control arms, so the CSX cars are not as "original" as the Kirkham version of "original" suspension.

If you wanted a more traditional (but not quite original) suspension on a Kirkham, perhaps you could try sourcing the Shelby style suspension from Vegas. But who knows how much Shelby would charge you for their parts.

I think that Nick @ Acton Custom has worked on both, drop him an email.
He fabs this stuff as well..........

I'm only basing on that when I ordered my Kirkham 289 fia, I later called back and upgraded to the stainless frame. I asked Tom if that was a problem and he said no, but then added if I later wanted to change to the original style suspension it would be a problem as there are frame differences.

Now it's possible he was referring to the 289 leaf spring upper control arms. Kirkham still refers to my car as a hybrid as it is a 289 with a 427 frame, although interestingly, when you order a ss frame, the main rails are only 3.6" in diameter.

Perhaps the best bet is to call Kirkham and stop the speculation.

My mate Nick knows?

Let me mail him.
I had inquiries from Germany to change to tubular arms for historic registration reasons.
