CMP seat base size?

[Bob Carriere]

....not going made but almost.

I need to replace the saging coil springs for foam but not sure what density.

We are considering doing a sandwich of soft.... medium and hard density..... depending on price may make a few trials and drive around the back field to see which is more comfortable for the " "derriere". My coil springs tend to bottom and rattle my teeth fillings.

Also some foam will not absorb water as easily....tends to leak rain in a cab 11 !!!!!

any advice or comments based on previous expereince foaming would be appreciated.

Cheers
