It is too bad that aluminum parts arenít available, but, the steel ones will hold up better. A little while ago I bought a to20 with worn out aluminum sides and grill. Everything was well worn dented and mangled. I bought the new sides and front grill pieces here and am very happy with the quality. Also bought the hood support as the tracks were with the hood as extra parts.
Looking forward to getting into this project. Post pictures of yours.
