...any images of these I might not have seen? Visiting the Revs Digital Archive at Stanford University revealed to me Karl Ludvigsen's photo archive, which included every image he captured at Watkins Glen '70. An old Sports Car Graphic article penned by Mr. Ludvigsen titled 'Bad Day at Dodge City' utilized just a single image from this outing. For inspection of the archive stunned I was to discover no less than four underhood shots of the Challenger, wheels off shots of the front and rear with the latter revealing the fore and aft Watt linkage situated above the leaf springs, and much more.

...restrict your search to the year 1970 (or whatever might suit you) as well as to Ludvigsen and search freely. Watkins Glen and Bridgehampton feature, whereas the Duke Q. Manor Collection features much from the 1967 and 1968 seasons that I've not had a chance to inspect in detail. Yes - I'd thrill to see more if you might spare the time and energy. The bodyshell for #77 was filed out today in anticipation of fabricating subtle panel flares - labor intensive these. Kind thanks...
