289 Expansion Tank

Another question - what size is the inlet that connects to the radiator line? It looks to be about 5/16" but I would like some verification.

I have a pattern for the plate that bolts to the head. We were tooling to repro the tanks but decided against it.

Mine measures 5/16" OD on the main body of the tube. The barb is larger of course.

I've been traveling for a couple of weeks, so I'm just now getting back to my tank. A big thank you to Rick (Mark IV) for the pattern he had for the bracket bottom. With the other research that I had done, I think I have a fairly close replica of the bracket. Here is the main support and the pieces. The original Lincoln support is a little long and will have to be shortened.

This is how it turned out after bending and welding. I still need to clean up some edges and welds, but I think it's close to accurate (close enough for me). Any constructive critique would be welcomed.

And here it is with the unmodified tank in place. My next step is to take the tank to my radiator guy for modification and let him attach it to the bracket.

Any chance I could get a paper copy of the new bracket so that I can fab up my own? Or at least the dimensions?

I'm finally getting around to posting pictures of the finished product.
