39 seat springs

[V8 Bob]

I had similar issues with the stock bench seat bottom in my '40. The spring coverings were removed, springs thoroughly cleaned and checked for damage, but still ended up with a seat that was too soft and unsupportive.


The shop that did my interior finally talked me into pitching the complete bottom spring assembly after questionable quality and cost concerns of new springs were discussed, along with no guarantee of any improvement.


The alternative was simply replacing the spring assembly with 2 pieces of plywood, diagonally cut 2x4 risers, some wood screws, glue. and 2 or more layers of foam. The result is a firm, supportive and very comfortable seat that can be adjusted if needed by simply changing the foam(s) density.
