Here we go again! Zuffenhaus MS RSR project...

Thanks!

I was able to make more progress on the oil cooler mounting today; as well as significant strides on the driver's side battery box.

This is where I left off with the oil cooler duct yesterday:



To get the cooler properly positioned, I had to consider the route of the hoses through the front bulkhead/duct sheet metal, like in the RSR reference picture posted previously.

I started by sitting down and roughing some models of 30, 45, and 60 degree -16 crimp fittings and printed them as cross sections to mock up the hose routing.





This allowed me to visualize where the hoses would pass through the trunk, and make decisions about hole placement (and consequently cooler position)



Based on this, I've temporarily hung the cooler - it may be adjusted for height still, and it is very likely that we'll have to modify the end tanks to get the bumper over it (although I could probably omit the rubber isolators it's currently mounted on to gain about 7 more mm.)






As I mentioned, I was able to make headway on the driver's side battery box and fuse panel arrangement also.

The historic car had battery box deletions, so we're recreating those while visually backdating the trunk wall.

Here is the trunk wall and battery box roughed in, before trimming off the back of the box



And this is where I stopped for the day:



Battery box in, and cut off. I'll work toward making the blanking plate tomorrow; I'll have to determine the actual size of the brake duct hose that passes through it before I fabricate and install it, so some research will be required.
