I also have one of those, built when it was new. One of my cousins had the MPC curbside kit, which was also supposed to be 1/24, it was noticably larger than the Revell kit. The real cars had a wheelbase of 102.4 inches. If the kit wheelbase is approximately 104 mm, it's 1/25 ,, if it's approximately 108 mm, it's 1/24. When I re-do mine it'll be similar to the incredible jade green one I seen on the net a few months ago ,, any colour choice for yours yet? Oh, and I agree about the carburetors ,,, they're shite.
