Ford F350: Clutch Slave Cylinder Replacement. The Centric Style. 

I got the same exact truck

Good day, I'm in the middle of a refresh on a forgotten 1997 F super duty, aka f450. The thing sat in a field for 10 years. I can't find a rear gas tank for the cab and chassis frame. The frames are 3 inches narrow on the cab and chassis which make the 350 and 450 rear tanks different than the regular frame. Aftermarket didn't produce a tank because it wasn't in high demand. I wish I could find a used tank, but I live in the salt belt, meaning these trucks are rotten and none to be had here in Canada.

They have these same clutch systems in most europien cars now,,Where the throw out bearing is part of the master cylinder ,,Its a dumb idea,,
