I drilled out the holes in question to about 7/8" and then I turned some spacers on my lathe that would accept the correct socket for the arp windage tray nuts. Weld the spacers to the windage tray and your done. Unfortuneately I didn't take any pics of it when I finished. You will need to figure out a good length for the spacers and go from their.

Funny thing about his is I had to figure out how to make them longer on the small block studs. But there isn't a windage tray out there that would work with those short studs. as the oil pump is the highest point for any windage tray. Now you switch to my Big Block in my vette and I had to cut the studs off to get my moroso oil pan to fit. Go figure.
