Is the 14" wheel commonly found on early 740s properly called "Dersus" (which I have seen several references to, none of them in factory literature) or is it actually "Perseus", which is a constellation, and therefore makes sense with all the other wheel names, that are astronomical as well. I have these wheels on my 88 745. I also have a set of the 15" ones, (which may or may not be known as Dersus---or Perseus, as the case may be) unfortunately two of them are bent. The hubcaps are not the same. The ones for the 15" are a lot larger in diameter.

In answer to the original question, which wheels fit an 88 760, I believe all 15" and 16" 7 and 9 series wheels, up to 94 will work just fine but 14" will not fit over the calipers.
