Do you remember the QJS 144mm pump mod? He used a plate of aluminum instead of messing with the stock FX pump shoe. At least you don't have to worry about the front mounting tabs (cut them off the liner). The mounting tabs are still in the pictures but, are they really necessary if the plate is bonded to the hull? Use some metric threaded rod to sandwich it all together.
Just throwin a wrench in some gears for ya...
:beerchug:
Is there any more information on this setup? thanks
