I have a 1975 f250 4x2-is the rear axle vent bolt that holds the brake block still available? The local dealers don't have any books that go back that far. The vent is of type that has the crimped cap on it. I could also use the bolt that has the hose end on it if that is available. THANKS in advance,Mark

 

I just broke mine on my 77 f250.......Napa did not have one....but I ended up buying a 7/16 bleeder screw and turned the end on my lathe. Worked good!

 

P/N your looking for is D1OZ-4022-A 73-75 F250 Before s/n W20,001 (7/16-20 x 2 1/8")
D6UZ-4022-A 75-77 After s/n W20,001 (7/16-20 x 1 25/32")
Note: D5TZ-4022-A replaced by D6UZ-4022-A

 

Thankyou mikeoOoOoO,and 78f250lj, MARK
