pictures of the inside of a longitudinal, to route my oil cooler lines Options

[mrbubblehead]

hi gang. does anyone have a picture of the inside of a longitudinal? i mainly want to see the front half. i would like to see how the 90 degree elbow for the heater duct is attached. i am planning on running my oil lines thru the heater duct. up one side of the car and back the other side. but i dont want to come up that 90. i would like to either replace it with a 45 degree bend and rotate 90 degrees so the line will pop out close to the floor, then route around the inner fender well and then enter the front longitudinal section to exit into the front trunk. or..... completely eliminate that that 90 degree bend and come out of the long at a more gradual angle.

i will make a removable cover similar to this picture that i found. (IMG:http://www.914world.com/bbs2/uploads_offsite/i722.photobucket.com-12492-1378101172.1.jpg)

any pictures will help. i dont want to do exploratory surgery. i want to be least invasive as possible. those of you useing the heater channel as a conduit for your oil lines, how did you do it?

thanks for the pictures
