It is a lot more than that. The '68 through '72 442 Hardtops had different trunk and fender contours than the convertible. When doing this one, the first time, I cut the roof and trunk kid from an AMT '69 442, and grafted it to the Revell convertible body. Needless to say, it did not work. The second time, I used the roof, and quarters from a JoHan 442 body, retaining the front clip, doors, and part of the quarter panels from the Revell body.
After a lot of fitting, filing, sanding, puttying and eyeball engineering, I think I have a body that works.
The interior is another matter. The '72 442 Hardtop had the Cutlass S seat stitch pattern, which is not present in the Revell kit. So I re-did the interior to the proper specs. Johan's '70, which I based my conversion on, had a weak interior, with moulded in front seats and console, with faint detail at best. The Revell parts were much better defined, so I used them as a base. I used plastic sheet and rod, along with a little carving, filling and sanding, to "re-upholster" the interior. Sorry, I did not take any photos, but I think it came out fine. I used a combination of Johan and Revell parts to make the interior work, and I can tell you, it was quite a bit of work to get the "jig saw puzzle" of the interior and glass to fit in the body and chassis. The glass is from the AMT '69 442, which had to be trimmed to fit..
Last week, I painted and foiled the body.
Earlier this week, I fitted the interior, glass, and chassis. At this time, I am attempting to download pictures to photo bucket, which is fighting me all the way.
