Measure, Cut, Drill, Rivet…Repeat

   Posted by: kdavis

The installation of the cockpit and trunk aluminum panels is a bit of a mundane process thanks to drilling 100’s of 1/8″ holes in the panels and chassis, but thanks to some needed fabrication and design, it was a little less so this weekend.

Trunk:

I spent the weekend working through installing most of the trunk panels, including a substantial amount of work fabricating the aluminum panels and fillers for my dropped trunk mod, as well as cutting and attaching access panels to make it easier to get to the fuel level sender, fuel pickup, and passenger side rear body mount (which I’ll need since I’m doing hidden body mounts and quick jack delete.)

The dropped trunk mod required that I cut the original trunk panel, drop the cut out piece down 4″ and then fill the sides in with new pieces. The mod will add a bit of extra trunk space out of the wasted space above the fuel tank. The extra space is needed since I’m doing the rear bulkhead shelf and throwing in a subwoofer.

I managed to get the drop box all built, and most of the trunk drilled, sealed, and riveted. I still need to fabricate the new cockpit “wall” that will sit about 10″ behind the bulkhead shelf I cut in the rear wall.

Tranny Tunnel Cover:

I had a bit of an issue with my transmission tunnel cover, thanks to a bit of poor planning, and failure to pay attention to the filler panels in my box of aluminum. I failed to realize that the oval hole in the cover allows for different mounting locations for the transmission and shifter, and that there is a filler panel that goes in to allow for the shifter boot mounting.

Unfortunately, I failed to realize this until AFTER I had applied, glued, cut, and smoothed the vinyl on the cover, which is a bit hard to undo. So, a little rework to be done, which is always a pain, but allows for some good practice. In the meantime, I was able to fabricate a top filler setup so that the vinyl will have a nice smooth surface to adhere to.

I experimented with the best way to mount both the main filler, as well as the top pieces, and realized the even smooth rivets will show through. My best option was to simply use an adequate amount of aluminum tape to attach both of them. This is the same process I used on the dash, and it turned out great under the same vinyl, so I’m confident that the tunnel cover will be the same case.

Tip – I needed to smooth out all of the seams and wrinkles in the aluminum tape. I had a lighter in my pocket from doing my electrical (I don’t smoke,) which I found worked great for this job.

Audio:

I ended up changing my plans on my subwoofers. Originally, I had purchased some inexpensive subs from Parts Express, but unfortunately, I didn’t read the enclosure requirements closely enough. I realized later that each one required a pretty large enclosure, close to 2 cubic feet. The total volume of the area where I wanted to put the sub box is about that same amount, which left me with a very large box, a somewhat inadequate sub, and minimal trunk room.

The solution was to find a sub that performed adequately on it’s own (without having 2 subs), and also required a pretty small enclosure. The answer is the Boss Audio D10F 10″ Subwoofer, (see below). At under $40, and with good ratings, it should do what I need it to do. the best news is that it only requires a 0.5 cubic foot box.

The box I built is out of 3/4″ wood, and measures 8″ x 17.5″ x 11″, which after factoring the box thickness, provides the 0.5 cubic foot internal volume. I added a separate speaker hookup panel as well, and sealed it all up with silicone. Once I wrap it in vinyl and mount it, it should fit nicely, and look good too. It will also make for a perfect mounting location for both amplifiers (one on each side), so it all stays nice and compact, and it is easily removed as needed. I’ll hard mount the box to the trunk/chassis frame so that the low end transfers well.

The sub arrived today (quick from amazon), but I haven’t had a chance to test it out yet.
