Hi im planning on doing a swap to ralley gages but im having trouble finding the sending unit for the oil pressure, as far as i know GM discontinued this part. is there anyone who has done this that knows the new delco part number? I can find them from yearone ect. but they have to still be made and available at a local parts store? any info would be a great help thanks...  

Do you have a 60 or 80 psi gauge? Ames Performance
Engineering has both.
