ok i have the s-10 box..my stock pitman arm wont fit the box?..it appears my box's shaft is 1-3/16 and my p-arm is 1-1/16..the car is a 78 mailbu..anyone else have this issue? my search tells me my pitman arm should fit????..help..thanks

Did you happen to read the description of this item on that auction? The first clue is the word 'big' in the auction title.

"The "Big GM" Power Steering Box is commonly referred to as a 700 series Saginaw box. It was the dominant power steering box on almost all GM cars through 1977 & about 1/2 of all GM cars from 1978 to the early 90's. This box is distinct for its square, 4-bolt housing cover, as opposed to the round, ring-retained housing cover that the smaller GM power box has. This box features a 1 1/8"-32 spline pitman arm shaft."

The S10 box is not a 'big' steering box...

yup as long as you use the pitman from the box you should be all good..my box didnt have a pitman on it, i was told by whom i bought the box from to re-use my old one..my original one didnt fit..after trying to get the right one from where i got the box (one lost in the mail one sent that was the same wrong one i already had)..i bought one thru speedway.fit like a dream..problem solved but what a freakin nightmare!!

X2. I searched local U Pull It yards and picked up both Box and arm for $25. Fit great with no issues. Mine came out of 1st generation (boxy) S10 2WD.
