Thanks... the hardest part was the main gun. I basically filed down ( or sawed off ) the 75mm to the point where there was a nub, then I attached the bigger gun ( thank you Dragon Panther 2 ) to the nub, after 'rifling' both the nub, and the barrel...The rest is pretty much stock....
The armor plating comes from flat leftover parts, which I cut down to fit ( the turret, and the hull ).
