Such a nice Merc
Hopefully my dads Monterey will look nice once again in a few years. Sorry I never responded to your question about the push bar mounts. We've been busy and the car is still parked in the barn. There is stuff infront of it where I cant get underneath to look.
My dad had to move out of his shop, and we found CHP pictures of the Mercurys. Shows all the equipment locations inside. If I can find them again, I'll email some to you.
We'll most likely have to do what you had to do with your tank, so this thread is helpful
And for anyone wondering, my dad has a 70 CHP Merc as well.
