No I don't.

'71 is the last upright in a bus. I had to drill and tap the head for a temp
sensor -- next to the #4 exhaust so that the sensor is in the valve galley --
near the #4 exhaust valve spring.
Basically bolt-in. Biggest issues are where/how to mount things and where to
return fuel.
Fuel return - My first try at return was the defunct fuel vent -- bad move --
pressure build up cause gas tank leak. I now have it mounted in filler neck
and restored the vent system.
ECU - Under seat storage area.
MAP sensor - on fan housing
Fuel Pump - in engine compartment on l/h side with clamps.

ID -- it's a big mother -- it goes into an in-line fuel pump ~1.5" diam. x 6 "
long. the outlet is 1/4" that runs to 3 & 4 injectors then to 1 & 2
injectors, then to a pressure regulator and finally returns to tank.

Better than the Kadron's that I was using -- 14-15 city, 17-18 highway --
remember that this is an 1835 and a heavy camper (~3500 lbs) -- plus I pass
smog. I used to have to retrofit my old PICT to barely pass.

There all that were offered in duals. They do have a single center mount
throttle body -- don't know what size -- but I was told that what I have would
run best on my engine.
