Dom- Drill a hole in the pan and stick a universal dip stick in there. They usially have a o-ring on the outside and draw up with a nut inside the pan.
The hardest is part marking the dip stick to the level you need.
I just did the same thing to a Jeep with headers, and had to do some creative bending on the tube to get it through the headers. I cut down a extra long reach dip stick out of a old Dodge van and used the stock bottom markings.
If you want there are higher cost kits from Milodon, Moroso etc. that seal up to the pan a bit better and use a screw in tube that can be trimmed.
Many catalog racing pans don't have provisions for a dip stick. I'm guessing that it is done on purpose because each application on a universal pan sold is different, and
oil sticking it is a really, really simple thing to do.
Don't forget to check for windage tray clearance of you are using one and you choose to come in high on the pan.
