Maybe I'm sticking my nose in where it doesn't belong, but just keep in mind the volumetric differences between the two ends of your steering cylinder. You'll need more oil volume to turn left that right.

Yeah I know its not the ideal setup. That double ended is the way some go. I bought the axles from a guy who was upgrading to Rockwells. It was already setup for a single ended ram. The high steer arms were made by him in his shop. I would have had that expense of buying new ones too. I ended up buying his ram too. I am going to run a cooler and with all the line it should be enough fluid to maintain both directions. Its the way it was setup in his jeep.
Thanks for the question. That's why I am doing the build so I can get input from other people in case I haven't thought something out or just plain doing it wrong.

I only mentioned it to make sure you are aware. It works for heavy construction equipment, but might be a problem at higher speeds.
The solution is a bit complicated and I hesitate to relate it here, but you can calculate the area of the rod and add a compensating cylinder (one way) on the rod end. Cincinnati Milicron used to do it on their hydraulic milling machines. This is 50's tech, but it allowed them to get a + or - .001" accuracy on table motion with a servo valve, and no direct lead screw connection. Basically, your "orbital" is just a servo valve.
As I said, it gets complicated because you have to figure in the compensating cylinder's rod area into you equation. When I worked on the Cincinnati's, the compensating cylinder had a weird size bore to match the area.
I'm sorry if I totally messed with your head. That's what I do best.

Back on the fenders. Got the fuel door opening closed up. The opening had a rolled lip that made it easy to fit the filler piece in and weld. I completely welded the outside and put a lot of tacks on the inside on that lip.

Jeez 5.38 with a V8 and 38"s? 5.38 would be needed for a 4.0L You could step up a tire size or two and be completely fine since you have that V8 ya know

Yeah I cut the fenders big enough for 42s but they weren't in the budget for the build. I got the 38s/rims from a buddy who was stepping up to 42s in his rebuild. Price was good and the extra money will let me finish it for this year. Win some and lose some. Hahahaha

There is a lot of satisfaction in building something with your own hands, isn't there? That's what drew me to toolmaking. Taking a piece of metal and making something useful out of it is a grand feeling.

I do enjoy working on it. I'm ready to finish it though. Hahaha
Got the rear fenders done. The trim panel is trimmed.
How I think I'm going to set the tank. To keep room for the batteries. If they don't fit on the other side I'll center the tank.
Passenger side
When I get my battery boxes I'll see if they fit in the extra space. If not I'll back up and punt and try something else with them.
