I also installed the Morris Custom Classic 3 point seat belts. I like them but i have to change the angle of the retractor to make it easier to pull out when putting it on.
Here is the 40 gallon fuel tank. Fit very well, I just had to move the rear cross brace that the strap is mounted on in the picture. It was like it was made to be in that spot since there were already holes for it in the bottom of the frame, I think the top too, but I don't remember now. At the front I slit a length of fuel hose to put on the front brace since the stamping faced the tank and I didn't want it to abraid the tank. Also since the parting line/height for the tank is more than stock, so I welded tow pieces of rectangle tube, I salvaged them from my old treadmill, lol. They just limit the amount that the tank can go up. I lined them up with the humps at the top of the tank. Attaching the fuel lines is a bit of a pain, I kind of have to have the tank half way installed, it's because of the stiffness of the braided lines. Also for the filler neck, I used a couple of 90 degree hose bends and a reducer since the tank filler is larger than the body side. I was able to also hook up the filler vent.
The worst part was trying to tighten the filler hose clamps since I couldn't connect the hose until it was installed in place and with the reducer and two bends there 4 hose clamps, and 2 were very hard to reach with the body in the way.
Oh, I still have roof rack I don't want, lol. It is just taking space in my bedroom. I guess I can take it apart completely to ship it if someone wanted it, lol.
