I noticed that my small block fan shroud was looking a little loose today so I investigated a bit. It is made up of two side pieces and a connecting top piece, all riveted together. The judging manual makes no reference to the fact that it is a three piece unit as does the section for the big block shroud. The question I have is about the rivets that hold these three pieces together. Two of mine, One on each side, have pulled loose, causing the looseness that I noticed. Are these standard rivets or solid ones (mine are the hollow pop rivet style) or do I have something not original? In addition, the Judging Manual states that the shroud is painted semi-gloss black. Mine is a natural black fiberglass with a some visible glass grain. Is this correct or should it be painted? Last question, two of the bends of the shroud have lost their resin, but the fiberglass strands are still intact. Can this be re-resined (if that is even a word) by mixing up some resin and hardner, then brushing small amounts of this back into the loose glass strands?

Re: 66 Fan shroud
Gary, The original 1966-67 small and big block fan shroud consided of three pieces. They were bonded together with a bonding adhesive and didn't use any type of rivets. I would think that you could clean the area that has bare fiberglass showing with acetone or lacquer to remove any oil or grease and reglass the area with the resin like you stated in your post. Sand the area smooth and paint the shroud with a semi gloss like Krylon # 1613. While you have the shroud out to do this it would be the time to bond the three picecs together and fill in the holes made by the rivets. Page Campbell #2299 -

Re: 66 Fan shroud
Page, thank you for your help. I now have the shroud out, cleaned up, and I will repair the weak areas then bond and paint. I also use the Krylon 1613 a lot because I like its color and ease of use.
Does anyone out there have a good bonding agent for these pieces or will resin and hardner work if the bonded surfaces are rough sanded and then put together with resin?
Thanks, GaryComment

Re: 66 Fan shroud
Gary, I use Vette panel adhesive that I pick up at my local paint and body shop shop supply store. There are two kinds. One is used for 84 up and the other is used for earlier models. The labels are somewhat confusing because one is used for bonding one and filler for the other and vice versa. I can give you the brand name if you like. Just rough the surface up with 80 grit in the area to be bonded. Paul 5962Comment

Re: 66 Fan shroud
Paul, I have a very good paint and body supply shop near me. They ususlly have the odd sort of stuff, like fiberglass stripper. If you will give me the name and part number, I will give them a call for ordering the adhesive.
Thank you for the help.Comment

Fan shroud update
Sometimes you find out more than you want to know about your car. This morning, as I was cleaning the fan shroud, in preparation for bonding the three pieces together prior to painting, I noticed that the bottom lip of the shroud, where the two bonded surfaces will meet, has the name "General Tire", "GT", and "DS" stamped into each half. In addition, the part number of 3886886 & 3886885 is stamped into the inside of each respective side. The third piece, the top part, has a similar number stamped into it but it is partially obscured by the bolt holes where it mounts to the core support. There is no doubt that this fan shroud was meant to be riveted together, because each rivet hole is uniform and matches exactly the corresponding hole of the other side. In addition, each rivet hole has a rectangular depression around it that mates with a similar but raised rectangular mound on the other side. Has anyone seen or heard of General Tire making parts for fan shrouds? This unit fits exactly with no cutting, bending or distorting to get it in and out of the car.
Thanks, GaryComment

Re: 66 Fan shroud
The brand name is Evercoat Plasticworks. Vette panel adhesive/filler in a black can with a green panel and white and yellow/red letters. The part # is 870. It comes out of Cinncinati where all good Vette purveyors are. I believe that it has limited shelf life and does not freeze well.Comment

Is this any help?
In the October, 1966 Chevrolet parts catalog, the '66-7 fan shroud is listed as three separate pieces. The part numbers for the small block are 3886885 (left), 38886886 (right), and 3888268 (upper). There are three separate, but almost identical, numbers listed for the big block. There are no '66-7 Corvette fan shrouds listed in this catalog as complete units with a single part number.
The parts history section shows the above part numbers were introduced in January, 1966, as direct replacements for three other part numbers. Perhaps there were two versions of this shroud - one to be bonded, and one to be riveted.Comment
