Re: 1988 Gmc crew cab build

Well if all go's right the motor will be in this weekend , Lot's of work finding all the parts to move the ac and alternator up and make some parts, also nice to know that with the after market motor mount that with the 47rh trans will sit right on the trans cross member with out having to move it at all just used a stock 4 speed auto trans mount, This is such a easy swap todo.

Re: 1988 Gmc crew cab build

did not have to mod the fire wall , with the motor mounts I got it sits on the stock chevy fraim horns and didn't have to move the trans cross member , just had to use a trans mount for a 4 speed auto to get the mount to bolt to the 47rh trans

I'm surprised that nobody has chimed in yet. Mine doesn't have cruise control so I'm not sure. Sorry.

Re: 1988 Gmc crew cab build

You can tow and put that camper on it even better with a bagged truck. More overall control and easier to load and unload.

Re: 1988 Gmc crew cab build

Looking good. I would recommend dropping your tanks, removing the electric fuel pumps and extending the draw straw if you haven't done it. Keep us posted with updates.
