Just beginning work on my project 65.5 convertible. The trunk has a lot of mustard colored adhesive all over. Was this factory or PO applied? Also, I see gaffers tape over the tooling holes above the frame rails. Was this factory?
That would likely be your 64 1/2 convertible
The tape over the rear most dolly tie downs is unusual and not what is usually seen there. Normally we have the rubber plugs in each. Looked at original examples built before and after your cars likely completion date to compare. After looking at pictures of unrestored Mustangs built around the same time period and plant it appears that Dearborn had some problems getting those plugs or were instructed to use the tape in those locations based on my findings. A couple of examples below. Very unusual and not something we would not normally expect but with yours we have a sampling that supports the practice
The use of spray adhesive under the trunk mat was a common practice at all plants into 1970 production. With that said and after looking at other cars, same plant and production period they have ALLOT less adhesive but maybe the worker got carried away allot on your car for some reason or the tip of the applicator came off so he just did what he could. Believe that something took place like that as it appears to be the same adhesive and sprayed in the same areas and pattern just allot more of it . Examples again below
First a very nice unrestored convertible from the production period that matches your's as best we can currently know. With a VIN of 5F1356xx. Much lighter application of adhesive but basically same pattern
Another example from the production period approx 5F13000 or possibly 5F12500 or so to maybe 5F140000 In this example again a thin adhesive pattern and what looks to be evidence of possibly what remains of black tape as used elsewhere on these cars. VIN 5F1376x
This example is shown in the Unrestored Section of the site. The car has been repainted at one point and some black rattle can also in the trunk. This may have coated over the factory adhesive we're discussing. The interesting thing that ties it to this thread is the use of tape over the dolly holes. We know what we see (silver duct tape it appears) was place over the holes after some painting, but why. If the plugs were there there would be no need and if there had been tape there before did the peron just remove what was there and reapply what they had found. Car fits the production period or just before with a VIN of FF1279xx
And lastly an example possibly after this practice so that we can start to look at when they stopped using the tape and went back to the rubber plugs and it also shows a better and closer look at the spray adhesive application on the drivers side at least. VIN is 5F1512
Corey Bowcutt: It would be interesting to know your cars sequential number or at least the first four digits
So that is what I found in my labeled picture files. May have more but won't know until I check there
Hope this helps
