As we all know there is hardly ever a trunk lid included when you buy a Model A Coupe / Roadster. Where are you guys buying your steel / fibregl*** replacements? I bought one for a '36 years ago from Wescotts. Very nice but now they are $800 for a Model A. As a side note I found a '33 / '34 coupe trunk lid (Never any of those cars around here) and am flogging on egay to get enought to finance a lid for a model A.
Brookville Roadster has a steel one, they want $490 for it. http://www.brookville-roadster.com/rod/index.html
Mac's Auto Parts,Bratton's, Sacramento Vintage Ford and the aforementioned Mike's-A-fordable all offer reproduction sheet metal,including deck lids. Pick the one closest to you-often if they're coming to show near you they'll bring it and save you the shipping and risk of damage.
If you have or can find can find a trunk lid with good interior metal you can get a new trunk skin from Brookville and re-skin it. My pal did that to his 29 roadster and it came out very nice. And . . . he knows zilch about body work. Six years ago, the skin cost $100., but more than likely has gone up in price. Taking note of the not very thick cardboard shipping box and how flat the skin was when received it looks to me like you could get some body gage sheet metal, have the edges bent on a sheet metal brake, cut some V's in the short angled side pieces and bend the flat piece of metal to fit the curve of the inner structure. After you got down to the bottom you could use some gentle persuasion with a body hammer to get the lower fold over the inner structure. Geez . . . I think I could do one of these and I ain't no bodyman either....
The reality is that there isn't that many places the make those parts, but there a lot of places selling them. Howell's does make a lot of parts, as do Brookville. I've bought parts from both of them and they were fine. Who does what and who's are better, I don't know.
