? dealing on the motor mount recall in the 70's

[Unreal]

I have seen the GM hold down kits for big block. If the recall was for small block only, were the b/b kits sold through the parts counter? I bought one a couple months ago. It was listed for b/b no a/c, no smog. I bought it anyway, and they were right. I also bought one for small block with air. It will fit my b/b with air, if I make a small bracklet to extend from the a/c bracket to the cable (less than 1")
