By turning the nut  on the end of the leaf spring in or out you can adjust the height of the rear & get it even & it doesn't take much. If the leaf spring is straight or slightly bowed up it's probably good. Remember all the leaf spring does is hold the rear up...the shocks keep it from bouncing.  I would look for another alignment shop.

The long bolt that attaches to the leaf spring on either side. On the bottom is a nut & a cotter key. This is the nut you turn to adjust for even height & it doesn't take much.  Make sure you have around 150lbs or so  in the drivers seat when you make the adjustment. I would replace all the rotten rubber first. You can go with rubber or poly. Poly will last forever but you should use a little white grease between the poly & metal,it'll reduce squeaking sounds.  If you replace the leaf spring with a fiberglass leaf spring longer bolts will be needed on the ends.

Alan, I'll have to take a pic this weekend and post it, but my car has been lowered.  My question is how to keep its current stance and not have the rear leaf spring bolts lower than the wheel!!!

Kind of impossible,The longer bolt is giving you the lower stance. The drawback is the bolt being lower than the wheel. Pray for no flat..........jack

Jack is correct, I think I have a 8" bolt in my 68 & it's pretty close to the rim. There are after market suspensions that are adjustable, but pricey.  I have the adjustable fiberglass leaf springs on the 68 & 73.  The 68 is adjustable ftr & rear for soft corning to hard (4 adjustments). You can really get deep into this if you want.

Just so I am clear, I like the way my car sits now, but the rear suspension bolts are very low.  If I buy and install shorter bolts, it lifts the rear of the car up, correct?

Yes you are correct, anything longer than a 8" bolt will probably be lower than the tire rim so if you get a flat ..gook luck. You can go to a composite rear spring ...I would suggest VBP. Give then a call & they will hook you up with the correct one if you go that route.
