This may be an odd question but getting a ton of mixed answers from restorers and historians. On a USA spec 246 GTS Dino was there any type of spacer or gasket used between the body and the bracket on the bumperette? Is the bumper bracket bolted directly to the body? Thank you so much in advance for any direction!
there should be a round rubber "grommet " fitted to the body where the bracket comes through. not sure of a source for them.
Exactly what VROOM said. If I remember correctly, the grommets have 1 1/8" diameter. I remember procuring them somewhere and just cutting out the middle groove. https://www.amazon.com/Rubber-Grommets-Inside-Diameter-Groove/dp/B0782S86R8 is likely what you need, but please make sure the inside diameter is correct.
I am understanding the question a little differently and am thinking it is referring to the fixing on the side where the bumper meets the painted body. My best research indicates that there was never a factory rubber or gasket in this area. That said almost every Dino you see will have some kind of rubber between the bumper and body on this mounting point added after paintwork because a repair shop will recognize how it is good form to put something soft between the chrome bumper and relatively soft paint. From a purely historical perspective my answer is that there is no gasket but from a practical perspective a well made gasket can be near invisible and prevent paint deformation and damage from bolting the bumper to the paint.
Looking at Table 110 of the Spare Parts Catalogue, it does not indentify a rubber washer as Rob has already indicated. It makes sense to protect the paint and not directly mount the bumper to the body panel.
The topic was covered a while back in this thread https://www.ferrarichat.com/forum/threads/the-bumper-grommets-thread.307928/
Sorry, I forgot about this book. I have only seen the M series bodywork spare parts catalog. I didn't realize that there is later version of this available. Image Unavailable, Please Login
There isn't a later version of that book to the best of my knowledge. The bumper grommets for the US models are shown in the spare parts catalogue on TAV.110. They are item 9, part number 111996000 Rondella elastica (elastic washers is the literal translation). Image Unavailable, Please Login Image Unavailable, Please Login
