I don't know without taking my hookups out again, but here's how I did 
it:

Get the whole set, if you need it, from Bus Depot or similar with the 
gaskets. Lay the plastic parts out straight on a piece of cardboard, 
tracing the outside of each, marking the holes. Cut out the interiors 
and punch small centers for the holes. Make SURE you can mount your 
plastic pieces to this, if you can't then you don't want to cut 
anything yet. Adjust the template until it fits the plastic pieces 
perfectly.

The pieces should be spaced about 1/8 inch apart. that's from 
observation, someone who knows may tell you differently.

Now it's time to transfer this to the car. Again, from observation, I 
placed the centerline of the left-hand unit (distance between mounting 
screws) at the centerline of the flue vent cover, so that a plumb line 
held at the flue vent cover would pass through the center of the 
electical hookup, which I think goes on the left.

The top of the plastic units should be 3/4 inch from the groove in the 
body panel.

Cover the area with 2 inch wide masking tape. transter (trace) the 
template to the taped surface. Whatever tool you're using (I used a 
jigsaw) be sure to allow a tape area to accomodate the "swing" of the 
sole of the tool when you work.

Don't remember the drill I used for the self tapping screws, but choose 
carefully--the screws supplied with the kits aren't very forgiving.

Hope this helps,

Jim
