I ended up purchasing hedmen hedders 69088. Hopefully they work. I think I may be tweaking my fuel line, evap line and rear brake line to make them fit. As far as the clutch linkage goes, under the reviews a guy put them on an 81 c10 and said it did not affect his clutch linkage. Should be coming in Monday. I'll post some pics with clearances and how far down below the frame they hang.  Anyone use these on there truck?

They look nice, I haven't used Hedmann in decades though, back when they were cheapies.  They've come a long way since!  Looking forward to installed pics.  8)

Only have the port side hedder on so far and I am very impressed with the fit. Have to rework brake and fuel lines a little to do the starboard side (which i installed, probably not in exact factory locations). Like VZ said, plenty of room for the clutch, clears the frame and motor mount and is pointing perfect through the hump in my crossmember. Bottom of collector flange is about 2-1/2" down from the bottom of the lowest part of my frame. Truck has a 2-1/2" drop in the bow, and a 4 in the stearn, collector flange and lowest tube is 10" off the floor.

Very happy with the fitment. Passenger side is on, had to adjust the fuel and brake line a little. But the fit nice and the collectors couldn't possibly be any higher and work with the stock crossmember.  Only concern I have is the fuel might get a little hot and cause vapor lock. If so I will re-route the fuel line.

That is a really nice fit!  So much easier without the body in the way!
