Your right, only the rear cap has a positive locating method to install that cap. As for the others, you have to do the feel and scratch method with your finger or nail to get the caps aligned(crank removed). Once you get the cap located front to back, and side to side, you place some Dykem⢠on the parting surface at where the cap faces meet the block and scribe an outline around the caps in question. Then once you install the crank, line up the scribe marks with the caps. Thats as close as you will ever get to aligning the caps with the crank installed, unless you dowel those caps as well.
