I'm no '67 expert, but Noland's Vol 2, pages 436 and 437 describes the differences, and has drawings. Seems that the top distrib shield for '67 big blocks with U69 changed to #3900517. Other than that, the only difference between single 4 bbl (L36) and the two tri-power versions (L68 [400hp] and L71 [435hp]) is found in the front grounding clip (riveted to the front of the shield). L36 and L68 used front clip 3904852; the 435 hp version used 3904855.
