The 35 radiator cap is riveted together and considered non repairable. The gas cap is also riveted together. Bob Drake makes very nice replacements for the radiator cap $$ but it has a brass rivet in the center which is 36 the 35 has a steel rivet. The gas cap is not reproduced since it is non vented, but Drake does have a vented cap that does look original. The repair kits I have seen are for the 33-34 car and commercial radiator cap and 35 Commercial cap, not the car in 35. If your looking for a lower cost replacement I believe an aftermarket cap was made by Everseal R-1 but it does not have the bail on the top.
