Dang I hope you kept the old foam ... new foam isn't latex foam and not as "good a feel" as the old style. heck, I'd pay a bit for that foam and shipping if your going to throw it away.(got a set of 66's that don't have any bun foam at all) I'd repair that in a heartbeat. Using landau contact cement and 20lb density latex 1/2" foam on the seat bun area and I'd be in heaven. 1/4" pink foam(latex not needed and pink or blue 20lb foam is more durable but not a better feel) for the bolsters and canvas to cover the springs. Then grind (no knives used here at the 60's lincoln leather shop) just a new 4" 80grit disk on an angle grinder to shape the new layers of foam. 1/3rd the money and pretty much a guaranteed fit too with the original "new seat " feel.
