Simple and easy.so i finally got the pieces needed to make a ultimate Venom.First I took the new Marvel Select Venom various heads and put them in my Spider-man Classics Venom.I already had a neck peg made before on him,from his previous head transplant, so that was a easy direct pop in replacement for the heads.After that I never really liked the short chunky arms classic venom had,so I took Select Venom's biceps and arms(not shoulder) with heat and pop,and they were a direct replacement to Classic Venom's arms.Then gave him a simple black repaint for the mean time. And vuala a new and better Venom in scale with legends and with the same goodies as Diamond Selects Venom!!
