I'm looking to pad my THIN '71 240Z seats. I can only find foam seat inserts at MAS or Datsun Restore. The prices are $86 and $90 respectively. I assume these are the identical product both sell. Are these two sources my only option? Alternately, is there a later seat that fits properly and is cost effective? I don't race my Z and am only looking for comfort and style to match the period of this car.

MSA sells seat foam also. IIRC at about $80 per seat.

To my knowledge all of the seat foam out there for sale is manufactured by "Seatz". (a company in Los Angeles).

I think there has been several threads about replacement seats in the past. Might try a search.

I believe mine are from Datsun Restore via Chloe. Worked out fine. Carl is right I think that both kits are the same.

I got mine from classicdatsun.com. I think they were about $200/pair.

Was it worth it? Did the comfort quota go up dramatically? I will go this route to keep the stock seats or look for alternatives (Miata, Prelude, etc.) if the cost and trouble of the new foam isn't worth it.
