Radiator conversion

[Smiling lemon]

I did the pepper trick and seems to have sealed it, this has been a couple months now and I had been looking into the conversations but there's not a whole lot of information.

The site pd6 posted have a 3 inch with dimensions that similar to my current read.

I think what I'll start trying to find is the dimpling on a 3-4 core, but still a copper brass setup, that way next time this happens I can repair it
