Drum brake specs needed

Anyone have an old book with drum specs for 49 pontiac front and rear? Thanks

 

If you dont get an answer here, I'll look it up at home later. I am @ work,and dont have access here. Sparky

 

I searched my books,and didn't find any brake specs. sorry. did you try a google search?? Sparky

 

here goes. 49 Pontiac, all models.Lining Dimensions; F & R 21 &5/16" length. Front 2 & 1/4", Rear 1 &3/4" wide, thickness 3/16. Shoe clearance .015". Wheel Cyl bore size F. 1 & 1/16", Rear 7/8".
Hope this helps.

 

What I need to know is what is max inside diameter for the drums after they are cut. I think they are good but guy that cut them said he thought they might be too big.

 

don't know if this has the spec or if any of the other manuals they have will, but here: http://www.tocmp.com/manuals/Delco/1949/1949DelcoBrakesManual/index.html
