Denis,

I would be a little wary of using our numbers on a Contemporary, at least on the driver's side. Our early cars used the original "OEM" factory replacements, but we moved the pipes a bit forward when we lengthened the footboxes.

If you can't get the numbers from a Contempory owner, I think your best approach is to bolt the primary pipes on and use the sight, cut-and-try method.
