wtb/ blue centers for 1/2 ton lockouts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Looking for a set of nos blue centers for the factory 1/2 ton locking hubs.

Anyone know if these are still available from GM, or have a part number, my dealer is not the best at helping locate parts for anything older than the 80s.

Try 3979551 - 2 reqd. 1968-72 Ser. 10 4/wd , Blazer (K) Knob, actuating (Dana 34916-3)
Checked my parts source and was told that all knobs are obsolete. Red and blue half, blue and yellow 3/4.

i may have a pair of used ones i'll check if you'd like??1/2 ton blue spicer right??

Kevin, thanks for the numbers, I figured they would be obsolete but it was worth a try, I didnt know they made a red center too, must have been a ford part or maybe on 73 up chevys with manual trans?

baggedblaz, I probably have 4 sets of used ones but they all are really faded, if yours were as bright blue on the front as the back I would be interested.

blazerman i'll check but i don't think you would be interested in mine then i ended up sanding and clearing my last set kinda helped make em shinier... but i'll check anyways..

Actually I have seen a blazer (69) with red, almost pink centers.
My 72 parts book makes reference to them.
