Yes, many people here have just the shackles and a TBAR crank or just an AAL and TBAR crank, with the tbar crank you can raise the front 1--1.5 inches and with the shackles or aal you get a solid 1.5 inches in the rear. This would give you a little height till you get you new UCA's (then you can add the other part then, either the AAL or shackle whichever you didn't install yet). Also Calmini owns this messageboard and checks it often hopefully they will see you posting about this and maybe try to help you out more. Although I had a friend last night call and speak directly to them without a problem so in your case I am confused . When I have spoken to them directly it was about 3pm Arizona time and was able to get through each time.
