I put one in my 73 Challenger and I love it. I'm able to get a little recline to it, which helps my bad back. I'm 5'10", and have plenty of headroom with it.

Make sure you buy the 2 re-inforcement pieces that go under the floorboards where you bolt down the 6-way. Might rip the floorboards if you don't use them. They are re-popped...
