The fuel tank riser can be removed if you drill out a bunch of spot welds. I used the original seat in my 37 because all the buckets I tried just didn't fit or sit right. You will have to move them to far forwards at the bottom to get the back to recline in its normal position. You will then find the pedals and wheel will be to close, unless you are really short. If you move the seat bottom back, then the back portion will be to upright and will feel funny as well. You will want to try them before laying down any cash. Rear seats from mini vans are suppose to work or a cut down seat from a later model pickup. With the right foam and rebuild, the stock seat feels pretty good, at least to me anyway. Joe
