Yep, coil springs in the rear on this cart, with 3" spacers under the springs & the shocks. So I will be in search of a spring option to stiffen things up a bit. I will probably cut the front of the bed so the angle is the same as the angle on the back of the seats & the two meet up with very little gap. And I'll need to figure out what I'm doing to do with the rear roof supports. I'm thinking about making uprights out of 1.5" tube & mounting them in the front corner of the bed.
Just installed a relay on the fuse box like Doomsman sketched up for me in another thread. And while I was at it I rigged up a 12v outlet too. Everything goes on & off with the key now.... headlights, taillights, 12v outlet, & stereo amp. Everything works great. Thanks D!
