I have a 1950 3100 with 235 engine, that I am trying to remove, but it will not come out! The whole front end of the truck is removed, nothing in the way at all. We hook onto the engine, lift, but the studs on the motor mount need to be lifted clear to pull the engine forward. Trouble is, when we do that, the engine is up aginst the firewall, and will not clear. Anyone know a simple way? Thanks for any help.
