1976 Rear window deflector

[ArizonaK5]

I'm got myself this rear top window deflector. Need some help on how the deflector was mounted to the top? Nutserts? Pictures would be great. Scott

You use rubber nut threaded inserts. see attached. They sealed the hole in the top as they are tightened to hold the bracket. The deflector has three L shaped brackets that attach it to the roof.

Thank you for that! Are the 10/32 the correct bolt size? On the rubber grommet the wide side is toward the wind deflector brackets?

 

[frankin5]

If you have the brackets and screws, you will need to match what you have tread wise. The flat side is the part between the the top and the brackets to seal the hole below.

I'll check mine tomorrow. I got the spoiler and hardware off my old burb...

Yes, the flanged end is what seals the roof, between the bracket and exterior of the shell.

Now that I think about it, I'm surprised the rubber on one haven't failed. Been up there at least ten to fifteen years, probably should make sure its all still in good order!

I can't remember what was used from the factory, I want to think it was similar to what they used for the door mirrors?

Now for mounting location on the top? I don't have the deflector yet and my K5 is a the body shop. Will the brackets self locate the mounting height?

 

[frankin5]

There is no adjustments. The brackets have a curved surface that set the angle of the deflector. It is best to have it all together and set on top to get the proper location for the mounting holes.

I don't have that old burb anymore, or I'd show the rivnuts too...

Easy peasy...

 

[frankin5]

I think the correct term is well nuts. The screw tightening expands the rubber to seal and secure the bracket.

Great. I'm sure I'll be able to handle it from here. Thanks again Scott
