I bought new brackets from Fusick to go with my new sunvisors (1970 Cutlass), and went to assemble them last night only to learn that the brackets didn't provide anywhere nearly enough clamping power to hold the visors up. I had the clamp screw tightened down as much as I could. Anybody have suggestions on how to overcome this issue?

I've tried compressing it in my vise but it seems to spring back when released. Just one more #$%@# aftermarket part with crappy fit.

 

The traditional cheesy fix was to shim / wrap the metal arm that extends into the bracket with medical cloth tape to increase the diameter of the rod which that bracket is supposed to grip.

Duct tape might do the job too, but I’d shy away from electrical tape personally. The cloth should help the visor stay in place a bit better.

Do the visor mounts have the plastic bushings installed?

Look at McMaster Carr for something that will act as a sleeve metal or plastic. You may get lucky with several ID/OD combos.
You could try "staking" the visor rods. 3 small stakes in a row 3 times around the circumference. Or like a battery post...shave off some metal where the two halves come together to increase the clamping force.
Then call the supplier and tell them that they got it wrong! Or should I say tell them to translate that to the supplier in chinese.

 

I just slid rubber vacuum fitting caps over the pins that snap into the brackets in my convertible's sun visors. Buy a variety pack because it will take a bit of trial and error to get the right size.

 

Yep, tried the ones that came with the new brackets as well as the original ones, no difference.

I tried using some medical tape as previously suggested but it was too thick, teflon tape, heat shrink all to no avail. It doesn't take much added thickness to make installing the plastic bushings difficult at the risk of damaging something. Two layers of heatshrink with no bushing wouldn't feed into the bracket without getting snagged and bunching up. The current status is using some sheet styrene plastic shims which seems to be holding them in place for the moment. We'll see if it's effective in changing temperatures and bouncing suspension.

Shaving metal wouldn't solve the issue, the clamp doesn't fully close although the clamping bolt reaches the point of being pretty much impossible to turn further. Perhaps the casting metallurgy isn't as flexible as the original material? One thing I meant to do before my last assembly attempt was to measure the new sunvisor shaft to see if the diameter is smaller than the originals. Hopefully I won't have cause to pull them apart again, but if I do I'll try to remember to check that!

I'll give that try next, if there's a "next".

 

When I replaced the plastic bushings on my convertible the RH visor would not get tight enough to stay up. I had some extra bushings so I wrapped one of the extra bushings with metal HVAC tape. Just one layer of HVAC tape on the outside of the plastic bushing then tapped it into place was just enough to do the trick. The thickness is around .1mm.
