Thank you all for the links and the information. From what I understand, the second GEN spring perches do not have the offset in them that the early ones deal, and just from looking at the photos of new old stock, the bolt holes look slightly different. I will order a set of reproductions from D&R and using the original as a sample see if I can tune the reproductions up to look more original. I have the fixture to true housings and all the associated work so that’s no problem. Thanks again.
