Got the later style heads and Jake's on the baby that's good, the photo is of the air horn (top) screen not the bottom so you don't spend much time on the screen thing lol.
I tried to order some bottom screens last week and found out they are no longer available aftermarket or Detroit just so you know your guy may not find one
Good to know about the screen, Leon at Big Mac diesel had a couple of motors and parts. Give me a blower, just had to pay for rebuild kit. So maybe I'll get lucky for once. Ha Ha. Don't know how good he is, but he turned the motor only for a few sec. and knew the blower was shot. I'm at his mercy now. all I can do is put it in Gods hands.
