Just an update.
I had trouble installing my tank from PBM due to the fact it was hard to find a fitting for the bleeder bolt. I didn't want to tap the head since I had already put coolant inside and no access to a drill. But I did find an adapter made my memco that fit perfect into my ka24de. Part was m6 to 1/8npt. They have a lot of useful fittings that can be bought in brass or stainless steel.

Works great so far. Just thought I'd let others know incase there were others who didn't want to tap the head and needed alternate decisions.
