Hi Scott,
The guys at Benny's are fun to watch. I feel compelled to see these gents succeed!
Mechanic:
I'm not sure who suggested that a body shop can't install suspension components. Pause for a moment and think about what type of work lands on their plate. They may not be replacing head gaskets, but it is *very common for body shops to not only replace suspension components, but to completely rebuild the surroudning mounting points. Think about your typical body shop that gets most of the work from insurance repairs (aka accidents that result in crunched fenders and bent suspension components).
Dashboard:
I need to hit the brakes ont his one as you have a few things going on. Firstly I wrongfully assumed that you had both the glass out, and the dashboard. Removing the dashboard is required to remove the wood. Removing the windshield is pretty much a prequisite for removing the dash (althout it is said that it can be doe with the glass in place). Removing the windshield will likely result in some minor repair of the lower windshield frame, particularly where the passenger wiper sits. That's a different ball of wax though. Figure several hours of labor to get the dash out. And several hours of labor to get the glass back in (it's a two+ person job). Their shop may have experienc with this since they do old hot rods. Twenty something guys doing inrurance repairs at a glass shop typically don't know how to replace the e9 glass. There is no glue, just a seal holding the windscreen in place.
Back to the wood. It appears that you have vinyl laminate over your wood. I think the big detractor for most is that this is oak. Oak has a very distinctive 1980's kitchen cabinet grain that is unmistakable, and not original to the e9 (no offense to the owners with oak cabinets
). Your dash is supposed to have veneer, which is actually under your vinyl laminate. The veneer is very thin real wood of the desired variety that is applied to a plywood base. I can only imagine that your veneer has issues and someone went to walmart and bought a roll of oak vinyl at some point in the past. I did the same to my 1970's bifold closet doors in my college apartment.
So, to fix your dash you need to remove the windscreen, remove the dash. Disassemble the wood from the dash. Remove the wood from the door panel tops (this is easy). Then send it off to Madera, Bella, or your local fine woodworker. One thing that Bela and Madera will do that a woodshop may not tackle is rebuild the plywood core where necessary. Earlier I mentioend the rust repairs to the lower windscreen frame. What happens is that water enters the cabin at that point and begins to delaminate the dashboard plywood. The veneer comes apart but more importantly the dashboard wood starts flaking like a slice of baklava. So with all that said, there really is no "while you are in there" opportunity to harness at the moment. You may very well return to Benny's down the road to do this work, but I suspect that they have no intention of removing the glass at the moment. If you pull that vinyl off now, you will only be disappointed with what is underneath.
Sunroof Drains:
This one had me curious so I took a look at my parts car. I'm sure this is well documented but I don't have a lot invested in sunroof specifics. The rear drain is two pieces. The rubber hose runs from the rear corner of the sunroof down the c-pillar. Just below the c-pillar roundel the tube exits onto a sheetmetal funnel (I must admit this took me by suprise). The lower hose connects to this funnel. The lower hose runs along the front side of the rear wheel wells. This is likely concealed by the rear window regulators (the shiny sheetmetal panels inside your rear quarter panels. The tube then drains into the rocker. I suspect the two piece design was to facilitate replacement of the rubber drains. I don't think that the upper drain attaches to any fitting where it exits into the funnel. I'm sure that Gary discovered this fact when he blew out the lines. The funnel isn't sealed, it just uses gravity to direct the water. He will definitely want to run air through the tubes on both ends to clear the drain. It is feasible that junk collects in the funnel but there is no real way to get access to it, even on my stripped parts car. These pics probably won't make sense to you but you may want to pass them along. I'm curious to know if non-sunroof cars have the lower drain from the c-pillar down.
Trunk:
As reiterated in this thread and your WTB thread. You can get everything except the brittle plastic pieces that Gary was concerned about (be careful with those man!). The deal with your car is that you have a US 1974. A similar looking replacement part is available from BMW for 1969-1973 US coupes, and they also fit 1974/75 euro coupes which didn't have big bumpers. Another member mentioned that since you are doing a skinny bumper conversion, you can modify your trunk to match earlier coupes. There is a big triangle shaped support piece which served to meet the 5pmh impact standards. Honestly not a bad thing to keep, but you could make your car look more "euro" by removing it, thereby allowing the plastic replacement panels to fit. It looks like you would just cut the piece to follow the original radius of the wheel well. If you decide to do this (assuming you won't), I can give you the measurements of the area so the shop knows what to cut.
