It puzzles me why noob got the height correct on the latest v3 gmtc but wrong on the subc. A shame they don't use a 2824 then it would have worked.
I've not bought the latest 3135 model and like you say the rehaut is not always aligned on this model.
I've decided not to bother trying to build a Franken subc as the financial does not outway the aesthetics when finished.
Gens will be cheaper soon I think as the subc does not sell nearly as well as its predecessor!!!
