Is that your cam plate we are looking at. I will post a pic (that may have come from Ron, and it looks like Jordans been there) so that we can help I.D which bits your talking about.
If we are looking at your cam plate,and the long clevis, then it all looks too close to the floor. Is the cam plate assembled onto the mounting plate correctly? If you can get the two pins(screws) out, then you can pull the rods out, and then make them the same length. At this point you can drop out the mounting plate(with the cam plate on it) and though the hole, check the rollers etc.
My understanding is that once you have everything set up, all you have to do, is adjust the brakes at the backing plate.
I'll also post another bit, that should be credited to someone from the forum.
Thers a bit to getting these brakes together correctly. Different coloured springs etc.
