My 67 came to australia as a full resto , interior was complete bucket seat console original blue sprayed black looks to be chevelle style trim pattern my problem is the front seats mount holes only line up with the 2 front mount studs and the inside rear stud the outer rear hole miss by 5/8 approx,seat runner on inside of bolt hole. If i flip seat over hole measurements are across front centre /centre outer holes measure14"" rear 13" back to front both sides is 14 1/8. Could these seats be from other GM car maybee nova? or is there some other explanation does someone have seats out to compare any ideas or help very welcome thanks

I just sold a set of 67 a-body seats a few months ago and from your pic, the seat looks correct, but I can't say for sure about the tracks being correct. I believe somebody is repopping the 66-67 tracks now. See if they have pics and dimensions on their website. Hope this helps. 64elkynss

Sounds to me that the car was a bench seat car originaly and was converted to buckets. When you do that you need to move the seat over like yours is to clear the seat belt. If that if the case your car was done correctly i think.
Its hard to tell without good pics of the seats and floor pan.
