Style Guard door edge molding "u" shape standard, #S39381.
I did not write down the angles, what I did to find the angle was to use an adjustable angle finder. Then cut the pipe at half that angle, that way the two ends will meet together and form the correct angle. Its a little tricky to get the pipes at the correct angles as the pipe also curves in with the angle of the windshield.
I tightened down the hose clamp till it collapsed the aluminum hose around the horn.
I would advise building the snorkel with the vehicle present, its alot of taking on and off measuring and fitting to get everything lined up right. Its a tight fit and you must have everything correct or its not going to fit well.
The screws I used are #10 self tapping screws not #12.
The bracket is 1/4" thick from the pipe and 1/8" thick from the A pillar and is just enough clearance with the 1/8" thick plate and screws to clear the door.
After thinking about the time it took to build it and the equipment you need, it might not make economic sence to build one unless you have the equipment or time or can bribe a friend with the equipment to help you out, just my two cents. Least you will need is a welder, grinder, some sort of cut-off tool to cut the hole in the decker panel and to open up the hood and interior decker panel to clear the 3" pipe, sawzall or chop saw to cut the pipe.
