After making my cage, I can no longer use the jump seats. I came across a rear TJ seat and plan to mount it in the back of my fj40. I know that there are plenty of you out there who are more creative than me so I am asking for ideas on how to mount it. I have a simple CHEAP idea of using wide flange I beam to jack the seat up 4'' so the kids arent chewing their knees on the trail rides. The only thing I dont like about it is it just looks bulky. Any ideas?
