So what I feared most has of course happened. Checked the mounts on Samson and they hit the radiator. Adjusted the offset on the lower mounts 2mm and they still hit. 3 inches worked but leaves only about 0.080" clearance for the fan. So that is too close, fortunately I believe I can fix it with a hammer. It will be hard to swing a hammer on Samson with the engine still in the car but I'm hoping to get a heavy duty zip gun in place. I just ordered this hammer chisel set. I think the 1.25" rounded hammer head will do the trick. Amazon.com: Astro Pneumatic Tool 49803 3-Piece Chisel & Hammer Bit Set .498 Shank: Home Improvement

These go into a Chicago Pneumatic CP717, it has a shit ton of power. If that works well I may even offset it another 2mm for tolerance issues.

I also moved the condenser 1/2" to the right to give more room for hose routing. You just cant get enough room for that. That required offset mounts

First picture shows the new lower brackets that move the radiator 3mm forward. The second picture shows a comparison between the new and the old. Third picture shows how the brackets are installed. They are clamped for the moment but will be welded in place. The 4th picture shows the modifications I needed to do to the lower radiator adapter pins to move the radiator 1/2" to the right. 5th picture shows everything installed.

Hopefully tomorrow I will be able to work on the fan supports.

Today my hammer tip came in and it just took about 1 minute to get all the clearance I needed. I finished up the top fan mounts but they still need painting. With that under control, I will re- fabricate the lower condenser mounts to move the condenser out another 2mm. Then I just need to fabricate 1 lower plate before I can weld everything in place. I expect to complete the condenser and fan installation by 2-12-2020. Hopefully by the end of the week I will have the Receiver Dryer installed.

Next step will be plumbing to the engine compartment. This will required custom made hard lines. That may take some time to design and order.

After that all work goes right to Samson. The sub frame will need to be removed to fit a custom made Compressor manifold and line set. Samson will be down for a long time at that point. With the subframe removed from Samson measurements will be taken like the ones performed on the stock sub frames back in post 30 to 45. The subframe will also be fitted into Ebola (My scrap car) and the M113 engine will be test fit in Ebola. Modifications will also be performed that will allow me to lower the M120 engine which had to be raised 1/4" to compensate for settling subframe and engine mounts.

And of course while all that is going on, I need to do a timing chain and turn signal switch on Delilah, my stock 560SL.

You never posted the picture you took in my garage. How did it come out? You, me and the 380 block. hahaha.
Didn't come out to good I should have turned the camera sideways. But me you and the one cylinder of the block are their.

Nice pic, guys! I guess the beers were cropped out. :) Amazing work, John!

We were done with beers by picture time... John had to drive. :(
Speaking of beers, have you tried the new Heineken 00 , less than 1% alcohol but tastes really great (and I am a beer drinker) They just introduced it here and they can't keep up supply.

Unfortunately these days I have to ask. How many calories?

I really don't see the point. Honestly.

You can participate in a drinking bout with buddies and then safely drive afterward.

I got the drier mounted today. Its a bit of a temporary mount as the material I have is too flimsily. I will be ordering some 3/32 steel to make a proper one. But it was good enough for evaluating the required line routing. AC line bending may be a challenge. I need to find someone who can put a 180° bend in a 3/8" tube with a 1/2" center line radius for the drier discharge tube. I also have some fairly close coupling of two out of plane bends required for the condenser inlet line. I have work arounds if those become to difficult but I would prefer to keep it as shown.

Looking at your diagram John, why does the 180 deg bend in the discharge tube need to be so narrow? Sorry if that's a stupid question.

Maybe rotate the drier so the bends are easier? Just a thought.

There are many solutions, but if some one has a 1/2" CL bending die, then whats shown doesn't require relocation of anything else. The standard AL elbows appear to be 1/2" CL. About the easiest solution is simply modifying the cross bracing and moving the drier down.
