Hey Craig,
Hot Roders have been exploiting a loop hole for years. These guys are putting fiberglass reproduction bodies on new chassis built from reproduction stampings. There were no records of chassis numbers back in 1932 so they just tell the authorities that it is a rebodied car on a modified original chassis. This comes in under a whole different set of rules which allow nearly anything within reason.
I wonder if the Kirkham would come in under the same loophole? especially since you can bolt original parts on their chassis etc? Just tell the RTA it was an old chassis you found in a barn amd the kind gentlemen at Kirkham built a new body for it
I think Mr Aussie Mike might just have to uncover a long lost stockpile of old Cobra chassis left over from the 60's in a old disused Melbourne warehouse.
Cheers
