Brake Questions - Help

Yes and yes. I only posted that 1970 manual so you could see the combination block A/J had mentioned.
All of the A-bodies were considered compacts.
When the Cricket and later Colt, etc, were added to the line-up, I'm pretty sure those were called sub-compacts.

I checked what I paid from Kanter, (doing business as old.parts on ebay) it was just under $200. Still not cheap.

* I should mention there was a change in drum brake hardware starting in 1969. So definately use '69 and up references when working with the drum hardware and shoes.

BTW, a few people on other forums that I showed the picture to said their opinion of that was it was a proportioning valve, I am asking them if they are SURE. All the paperwork you have graciously shared with me says they are wrong, even though I was hoping I would not have to add another 100$ part.
