Buddy bucket seats alternative?

[12secondnova]

Anyone installed or seen this style seat (in the link) in a 67-72? I think it would look very similar to original buddys if you remove the headrest and had covers made to match the factory pattern? I love the buddy buckets and after siting in my uncles 71 with them they give me more room than my bench. (I'm 6'6) I was wondering if I relocate the gas tank and notch out were the back meets the cab would it give me maybe an extra inch of leg room? I think It would also be cool if they did work to find some heated and cooling ones and get those to work, but thats a dream for another day... Any info would be greatly appreciated!
