I did use the sure fit kit originally. When I changed front clip to CBR I redid the A/C connection account I wanted everything I could out of the engine bay. My kit for the 67 had the heater hoses going through the oem location on firewall and A/C lines also (mine was not an A/C car).
I couldn't find any pictures I took of how I did it but it's almost like these that I remember Nova66mussl posted (hope he doesn't mind me using them). I did mount the dryer on firewall just to the left of where the lines go through on passenger side under the fenders. Again mine is 67 and this on a 66.
Also I changed the A/C lines and connections to EZ-Clip types as they are smaller OD and you can make them up as you go. Not trying to change the direction of your build, it's awesome as is, just something to think about in the process.
