Shame dragster chassis builders don't all have a regular code of identification, a 'VIN', or 'serial number' system that would assist in identifying a chassis at scrutineering. Or even at a later date, either for this purpose, or for 'approval' purposes in re-engining and re-bracketing, like a lot of the 'Nostalgia' cars would need, no doubt. That way a manufacturer could maybe 'register' a log of a chassis number with the details of the tubing used, date built, etc, and that way if a chassis was damaged, be a little like the DVLC thing where a potential buyer (especially if the chassis went through several hands) could check it out for previous prangs and potential 'handling difficulties'. Just a thought, as the chassis looks a little 'banana shaped' in these pix to me, would help identify it, surely??
