If you are talking about notching the fenderwell so the seat go's further back, I would think so. It's done on cj-5's all the time.. I think the only notch it a inch or two. Push the seat all the way back and cut out the corner section of the wheel well that the seat enterfers with and weld in new metal making a notch in that corner of the wheel well. I think if you google it you should find some pics of it.
