Did you replace the pickup with another or modify the existing pickup. I'm installing one in a 1973 Bronco and will need to modify the oil pan to provide clearance for the front differential.Yes, they will flip rear sump to front sump. You will need to change the pickup and dip stick.
jghflys,
Here is what I did with my 73 Bronco pan. It still uses the stock pickup.
