Seats and harness for a '71 CJ

Currently my '71 CJ-5 has the stock low back seats with the lap belts but I'd like to get at least a 3 point seat belt in there though a 4 point would be nice. The roll cage I've got in there won't work as well if there's nothing to keep you from whacking your head on the ground if you fall on your side.

I could just buy a set of seats and build brackets but I was wondering if there some that were used alot because they worked well. If I could find a set that were an easy swap that would be great.

So for those of you that have swapped out your seats what did you use?

 

I used the factory frames with bestop aqua's. I had to redrill 2 holes per frame to get them to fit. Very nice seat, no longer worryed about water ruining the seat.

 

I got the high back seats from my friends 72' when he replaced his, pretty much a direct bolt it.

 

I have corbeu suspension seats in mine. Very comfortable seat, but expensive and big for a jeep. I am short enough that the big isn't an issue for me. In my second I have the plastic racing buckets. Wouldn't recommend those as they are very uncomfortable.
