the wheel base changed for the b-body in 71. they went wider. the back seats are a different length. youll have to get ones out of a 71-5.the front buckets will interchange, but the back seats diff.

 

Hey Skymynx im sure its a long shot but you might want to check ebay and see what you could come up with and if they show nothing just put a post under want it now and maybe some one has a seat for you, i have found many parts that way

 

Skymynx i just checked for you and there is a rear seat there under item # 250331043717 and no one has bid on it so im sure you can get it for the starting price of 49.99 but the shipping is 80.00 he only ships greyhound and the bidding ends 11-30 so ya' got one more day if ya' want it but it looks like it will need repolstering ..... good luck

 

did you get a chance to look at the seat ??? it also tells you the different years that will fit
