Idea doesn't appeal to me, but if it does to someone else, hey, why not? There were all sorts of weird and wonderful contraptions being run in those days. If somebody didn't build that exact combo, they certainly COULD have.
I just bought, at Hobby Lobby, a product called Flex-I-File Plast-I-Weld. List price $7.49, with my coupon I was out the door for well under five. The label says Contains Methylene Chloride, which is the magic ingredient in all the late, lamented fast-dry liquid cements mentioned above. Haven't used it yet but I expect good things. I don't know if this product is brand new, or if HL just started carrying it, or if I just happened to see it for the first time today. Whatever. It looks like it might be the answer to the problem here.
Agreed. The real car dates to, what, 1958, '59, and ran through the early '60s at least. When I do mine, I'm gonna update a few things for more of a 1964-ish look and say that the car was updated to stay competitive (or maybe just that it's Green Hornet II). Very cool old kit and thanks to a couple of reissues, not particularly rare anymore. If all else fails, eBay should turn one up at a reasonable price.
If you mean the "new" kit, which came out in, what, the '90s?, I can tell you that the MPC '57-'60 tops don't fit it, and I don't think the AMT '62 does either. I don't know about the top in the Revell '62 gasser. I have seen, somewhere, where someone modified a top--I think it was the MPC '57--to fit. As I recall it was a fair amount of careful work, but the guy pulled it off. Others might know more.
Double Dragster, mainly for the Fiat half. That frame can be used for all sorts of early to mid '60s Altereds--Ts, Bantams, Deuces, whatever. I'm even thinking of using one for an early funny car a la Psycho or Colt .45 Mustangs. If you're only talking about the rails, I THINK I MIGHT like the Slingster better, but can't say for sure because I haven't built one yet. Both kits are "parts mines" and both lend themselves to all sorts of Modeler-Fu interpretations, variations, and modifications. Now we have both to choose from again. Is this a great planet, or what?
Does it have to be tubing (i.e., hollow)? I'd be willing to be you can find some clear monofilament fishing line about that size. You can also heat-stretch clear styrene sprue to whatever diameter you want. Getting it exactly to your desired dimension will probably take some practice, and you'll probably make several unsuitable pieces for every usable one you produce, but the price is right and it doesn't require any special equipment or unique skill.
