what are the correct ft wheel cyl's on my tk? 1 1/8" or 1" bore? my truck came with new cyl's and shoes/drums on it. all cyl are 1" bore, but i see two different ones. also bought new hoses from napa and they have the wrong ends on the cyl end. 7/16 inverted flair, the org ones just screw in (1/8?) with a copper washer. have seen somebody on here had adapters of some kind? anybody know anything about these adapters?

There's an adapter you need. PM JPBrecheisen he can point you in the right direction.

i know the adapter that you are talking about, it's an odd ball as a 3/8nf bolt screws into the wheel cyl. so 3/8" male sae nf to 7/16" inverted flair.

The gm part number for the wheel cylinder is 2412642 and 2412643 . Book calls it 1 1/8. Wagner number 34196 34197 .

I had the same issue at NAPA but they did have the 1/8 screw in type, not sure on a part number but on the hose it reads; SAE J1401 1/8 HL SUNSONG. Hope this helps
