Rubber body mounting blocks
 

I own a 1930 roadster and it tends to sound junky when hitting bumps. Would it make sense for a company such as Float-A-Motor to make rubber body mounting blocks to quiet this type of Model A down? Would rubber rather wood blocks make a difference?

have you ever gone thru and check your body mount tightness, spring U bolts, lubed springs, front and rear shackle wear, radius ball, exhaust system, brake cross shaft, emergency brake cross shaft for slop and wear? There is tons of places where things pivot and wear that causes slop or clunks rattles and bangs. Kinda like a modern 200K+ mile car is going to make noises until every moving bit is lubed/replaced.

NO!

Rubber is by its nature not a true solid, its a super viscous liquid. Over time with weight and vibration it will pancake and flatten out. This will cause the body to frame bolts to loosen and make things much worse. Most "rubber" mount blocks will actually be rubber impregnated fiber to keep some stability.

The stock wood blocks (of the right kind of wood) with a thin rubber pad work fine... just replace them every 50-100 years.

If you just had to change things you could box in the subframe cross channels at the body bolts but they would not be as strong as the original design (too much concentrated force).

The original body blocks had a rubber pad tacked to them. the pad was not just rubber, but had fabric moulded in, like the side wall of a tire. That rubber pad insulated the block from the body to lessen noise.
