# 1 when i got my truck from the PO it was already changed to a Automatic 350 from a stick so he cut the manual trans cross member out to fit the 350 trans if i want to put in a stick shift again does that mean i have to get another manual trans cross member and have it welded back in or can i just do the swap? and next question is can you put Linseed oil on a rattle can paint? or will it ruin the paint? asking here because i have tried to google it and cant find anything on it i know you guys use it on patina trucks only thing i can find about it is on wood lol thanks again for all your help
