Okay, but this all provided you have a Rockford-type clutch cover, which will have six springs in it. IIRC you have a SuperA.
With the pressure plate laying on a good flat surface, the new specs are as follows:
From bench surface to underside of cover: 27/32" (good for a or SuperA)
From bench surface, measuring through the center, to the upper surface of each finger: 2-23/64". For an A, it's 2-3/8" (1/64" more).
What's more important than the actual measurement, at least in evaluating where you stand, is the uniformity of your measurements. The stem end of a vernier or slide caliper can be locked down to give you a fixed point of reference.
The adjustment is made by turning the bolts (you'll have to loosen the jam nuts) at the outside end of each clutch finger. Move the first one until you get the cover within a 64th of where it should be from the surface. Then do the other two and recheck all around and adjust as necessary to get them even. Next check the height of your fingers. If they're uniform, that's a good start, but count on them being out by more than the pressure plate -- with the leverage they might be off by an 8th of an inch or more. Not a cause for alarm -- that's why you have a freeplay adjustment.
There is some latitude to be had, though I can't find a service limit/wear spec in any of the books I have.
Measure up and let us know what you find and we can go from there.

The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to. In such cases, rework makes what could have been a fun project turn into an irritant or even a nightmare. Minor Irritants To give you an example of an minor but irritating proble
