[B. W.]

These are all the numbers I have:
'71 GMC K25 dana 60 with 12" brakes

parking brake lever (inside of drum) P/N 5462841-L (left side)
(didn't record the right side, will check on Monday, mine's in pieces)
right side P/N 5462842-R

parking brake lever return spring ( sits between lever & shoe, keeps lever up on top of adjuster) Raybestos H2151-2

parking brake strut P/N's 5453803

I had a broken parking brake strut & placed a WTB on the parts board. I thought the Chevy trucks still ran a 52 in the rear in '71? Are your brakes 12" x 2.5"? This size was a one year only thing if I'm right.
