1970 Firebird Seat foam same as 1969?
Need new front bucket seat seat foam and cant find it. Are the seats and foam from a 1969 Firebird the same? Thanks.

From what I know, the foam is different, and there are 2 different seat foams for 1970 depending on if you have standard or deluxe interior...
Did you try Al Knoch for the foam? https://alknochinteriors.com/product...ird-seat-foam/ |

I did not know they offered foam at Al Knock. Thx.

1969 foam IS totally different from 1970.
Not that I am trying to seem contradictory, but the seat foam is the same for standard and deluxe interior; For 1970-1972 the difference in deluxe or standard seats were the covers. If you can't find any good foams; I have a set I pulled from some seats over twenty years ago - I had thought my seat foams were needing to be replaced, so I wasted a set of 1970 Firebird buckets... but my foams were fine, they just needed a tiny bit of repair. |
I'm hearing different plants used different foams depending on the year. And post-73, the seat frames are different for the rears. A mix of rear seat frames of some being a one layer frame, with thick foams that had springs in them, and 2 layer frames that had a thinner layer of foam.
I started a thread on it, and not getting much input, but am starting to think I may just 'convert' my rear seat frames to the one layer type, since the foams are very detail-formed. But am waiting to see if anyone can provide input. I'm not clear on the front seat frames & foams, in my case, I'm using aftermarket seats. . |

the rear seats can be grouped into three types - these are all my personal observations:
1970-1973: thick; spring and burlap/cotton backing behind covers 1974-1976(?); thick; frame with formed foam backing 1977(?)-1981; thin; frame with formed foam backing I mistakenly tossed my car's original rear seatback shortly after getting it, because I had a nice '77 velour seat in the rear; I ordered replacement seat covers in 2001(?), and quickly found out that the replacement seat back cover was too big. The replacement covers were obviously for a "thicker" seat back - and I was happy at that time that I kept both original seat bottoms - I ended up using a donor '73 seatback (from my former '73 Firebird; and it took a while to find another one for that car). It would be quite possible that the original burlap/cotton material was replaced by foam at some point after being built, but from my personal observations formed foam padding replaced the cotton/burlap material after the 1973 model year. I am not certain what was used for 1974, but I have observed that 1975 used the thick style seat back with a formed foam pad ontop of the seat frame. About the "different plants used different foams"; For 1970 & 1971 there were only two plants that built the F-body; Norwood Ohio & Van Nuys California. For 1972 & 1973 only Norwood built them. I believe that the 1971-1972 (front) seat foams continued to be used on the 1973-1977 'standard' seats - while the 1973-1977 deluxe seats used the "horseshoe" style seats which were to my understanding a version of the Grand Prix seat. |
That's good info there unruhjonny, thank you.
I should take pics of the frames and foams I have, and post for comparison and historical info. If I had good photos of the frames without bolsters, or the 3 versions, I might be able to mod the frames I have to use the thick, formed seat foams. Those I can see a benefit to, since they are in a detailed shape, and would hold form/shape longer. Ok, everyone, if you have good shots of the different seat frames and foams, please post. I will snap some of the ones I have tomorrow and post. . |
