For the experts on originality:
From photos I have seen, the normal SW
oil pressure gauge for the 289 street cars was the 90 degree sweep version (during the SW era). It appears that the USRRC cars like 2 4 5 8 and 2 4 5 9, and maybe 2 5 1 4 came with the street dash w/glovebox. I have some photos of 2 4 5 9 that show a 270 degree sweep
oil pressure gauge. I was curious to know if that gauge would have been the 0-80lb or the 0-100lb version... can't make it out on the photo. Was there any consistancy? Would it being a race version mean they used the higher range gauge, or the 80lb gauge like the street version? It is the smaller size 2-1/16" gauge, rather than the 2-5/8" race gauge.
