I convinced my wife to reupholster one more set of 69 bucket seats. The pair on my sons car went as expected with no springs in the seat back just as aftermarket catalogs show. I ordered same materials as prior seat (Foam, etc) and upon removing the upholstery the seat back on my 69 the frame has springs. According to Ames and Classic catalogs, only the 67-68 seats have springs in the seat back. Headrests on both cars have November 1968 date codes and upholstery date code is 10/68 in my car. Seems to be the real deal.

Does anyone else have the version with springs in their 69? The reason I ask is that the aftermarket catalogs show a differnt part number for the seat foam for 68 and 69 based upon whether the frame has springs (68) or not (69). Pretty sure the 69 seat back foam will be too thick. Prefer not to open the box if it will not fit.

Thanks for reading. John

How do you find the date code for the upholstery?

The date code is on the backing side of the upholstery. There is a logo, apparently the manufacturer's, "GS" then below it is the date code 10 68. I had 8 68 on prior seats. The logo and date code are repeated many times. Easy to see if you turn inside out.

Really hope someone else has encountered same issue. I really need to replace seat springs on the bottom as they are worn but don't want to proceed further until I understand what replacement foam to use.

There are difference between foams for the std and deluxe seats. I wonder if you have one set of each kind of seats.

Both sets of seats had original standard upholstery and both had date codes of October or November yet the seat back frames are different. I'm going to contact Ames to see if they have a tech support group. I'm guessing I will need the 68 seat foam inserts since those had the springs in the frame. The 69 foam I believe will be too thick.
