if your rad is really spare, i have a loop lacking a rad.
I fixed and remilled my old TT-Block today, and modded my tt pump with 1/2 barbs.
i use my old tt reservoir which has a damaged seal cap, but when standing flat, is surely useable.
im not that kind of wealthy^^ it somehow embarrasses me to ask for the rad
but with it, i could put the 939 from bogmali under water^^ would be better for points.
