1102200 was originally used on 1960 Pontiac listed as Heavy Duty generator on cars with Heaters. 35 amp 12 volt. If you have an original one it would be heavy duty with cast iron end plates and ball bearing on the rear instead of the bushing rear plate. Most of this type generator had a heavy duty wound armature in them and even though only rated at 35 amps instead of 45 plus, it would have handled higher output on a more continuous basis than just a typical wound 35 amp generator....this goes back to the heavy duty armature.
Delco 1102199 and 1102240 were the same generator and used in 1961 Pontiacs with V8.
There you have it.
