I am about done with my current projects (Elect CC and sup Vac pump) and want to get ready for the next project -- Sensitized Brake Booster.
I am working on my #2 coach. (1978 Birch) It has the late style dash and I can not see any access to the bolts holding the booster to the dash. I have searched the picture site but only found the early dash. (With leveling controls to remove for access.) But I haven't seen anything for the 77/78 dash.
Anyone have any good tricks to keep from chopping holes in my dash?

Mike, the booster has studs that project towards the interior of the coach.
The nuts are "kinda difficult" to access, but if you have double jointed
wrists it can be accomplished. The lower nut and washer on the drivers side
is particularly onery to access. You can use a wooden wedge similar to a
door stop and wedge the heater/AC ducting away from the aluminum floor and
gain enough space to snake a wrench up there to access the nut. Getting
started, I just stung a piece of welding wire onto the nut and fished it up
there. Not a picnic, but doable. It helps to be in the correct "frame of
mind" when you do this. This is one case where it would be very helpful to
have the engineers that design this stuff have a mandatory period of
working on it after it leaves the factory. They would soon quit designing
crap like this that have no access doors or panels.

Easy to say Jim, but in reality GM engineers routinely work in the assembly plants alongside UAW workers to experience what it takes to put these together and they also work hand in hand with service engineers who assemble and disassemble prototype vehicles as if they are in the repair process. Sometimes trade-offs are made that don't suit everyone, but they are not made without a lot of thought. My engineers would work not only in plants but we also spent part of our vacations working in dealerships.

Bob, I have experience working in the IGO trade without the access to all
the work arounds and service reminders that are available to those techs
working in the dealerships. I am sure that the brake booster is fitted to
the chassis before the body was fitted to the chassis. Under the dash is a
particularly difficult area to work on. On some heavy duty trucks, and SOB
motorhomes, the instrument cluster is hinged to tip down and allow the tech
access to that area without standing on his head under the dash. GM by no
means has the corner on the market in difficult vehicles to service. Even
the OBD connectors in SOME vehicles is a PITA to access, and one would
think that they would be easily accessible for service. Several european
foreign makes have a pod on the inner fender wells that house most of the
relays, fusible links and fuses and diagnostic connectors in one area. Sure
makes it nice, but somewhat susecptible to collision damage and corrosion
from water splashing. No vehicle is perfect, but some are better than
others. I am a GM trained technician, but my last service school was in
June or July of 1985, at the Tigard, OR tech center, long since gone. I
know with specialization in product lines, and offshore purchase of sub
assemblies by the factories trying to compete with what are some fairly
high quality products, that GM has it's work cut out for it. But relatively
low numbers in production like the GMC in a market that fell on its face
during the Arab oil Embargo of 73-75 did not help either.

G'day,
I realize what I am about to note is one - upsmanship!
If you think access to "stuff" on automobiles is bad try working on aircraft!
Military in particular, fighters being the worst!
Regards,
Rob
