Proper garage engineering forethought there!
Now this ol' Jeep needs a coat a' paint
But she makes up for what I ain't

Been plugging along. I feel like I’ve been spinning my wheels a lot but I’ve made some good progress. I like to think I’m taking my time and doing things right. The engine mounts and cradle took a long time. I had to figure out a design for the trans cross member which changed about 4x from what I originally planned. To do that I had to mock up the transfer case and doubler. I’ve changed direction on the doubler, doing a Behemoth Drivetrain Strongbox. Better ground clearance, lower gear ratio, lighter, potentially stronger. I am not using a factory bushing between the trans and cross member, I’m going to do the rock crawler thing and build it with round bushings between the cross member and the ends at the frame. I still have to order those parts. The main 2 reasons for the design are to keep the cross member above the front driveshaft and also I can make a secondary mount point on the output flange of the trans since the factory 2 bolt mount is a weak point. I took some pics of the x member but my phone deleted them sorry!

So so close to firing up the engine. Normally I get to work on it during the week but this whole week is slammed so I’m hoping to fire it up this coming Sunday. I’ve got the oil lines all plumbed, but as I was filling the engine oil I realized my valve cover gasket is completely shot so I ordered one of those. I will also have the fab parts to finish my trans cross member this week so I’ll try to get that bolted up before cranking the engine so I’m not chancing it rattling off the temporary setup.

Picture time.

Shaved some excessive bulk off the Ford 205 case so I don’t have to cut my floor.
Image

This used to connect to the factory oil filter housing but needs to connect to the new one with a hose so it had to be cut drilled and tapped for 1/2” NPT. This took about 2 hours with my rudimentary “machining” tools.
Image

This is what goes in place of the factory oil filter housing. One side is for an optional bypass filter (capped for now) the other side is the supply to the new filter setup.

Beginnings of the trans cross member. Cardboard is a CAD template for my secondary mount point which grabs 4 of the output flange bolts on the trans. This will be isolated with bushings at each end of the 2x2.

1/4” Steel I had my shop bend for the rear leaf spring mounts for my 63” springs.

I will have my new valve cover gaskets tomorrow. Took that apart, too end of engine looks beautiful. Going to check valve lash adjustment while I’m in there. I couldn’t decide what color to paint the valve cover. Felt like the blue would be too much. Either way I had to strip this down and hit it with some rust encapsulator. I got done stripping it with my Eastwood SCT tool and the nylon brush and it just looked so pretty I had to leave it bare. I hit it with 3 coats of Eastwood matte clear chassis saver paint. They say that is good up to 400°.
