Has anyone tried an off road seat or racing/sport seats in the minicabs? I'm debating with myself over the seats i see in summit and a few of the other racing catalogs. i know that there is no room to slide them back in my cab and i would have to overcome engine access, but would still like to try something other than re-upholstery. i had a highback set of poly-buckets in an old dodge dart that were verynarrow and vertical that i thought might work, but don't see anything like those anymore.
