Small Block Fan Shroud

The corner tabs on my OEM fan shroud on the 350 V8 in my '71 GMC Jimmy K/1500 are shot, broken off. The part seems to be either fiberglass or some dense poly-plastic. Not solvent to any glues I know.
A direct replacement would be best. Who sells OER SBC Fan Shrouds?
350 V8/SM 465/ 4WD/ originally AC-equipped.

Re: Small Block Fan Shroud

LMC has the best price on a repop . if you still have the broken ears using super glue with baking soda will repair it and last forever .

I'll have to check on the passenger side 'ear.' I do have the drivers side.

I used the Superglue/baking soda trick to repair an all-black Standard Wiper switch knob, last year. Only Deluxe knobs with the center metal dot exist in the aftermarket.

How good are the LMC repops?
Also it's a 4WD truck, but once had Air Conditioning. That presents two choices.

Re: Small Block Fan Shroud

I used some J-B Weld High Strength Plastic Bonder Liquid 0.85 oz#50133 on the plastic after market front bumper on my OT ride the other day after I got it hung up on a high spot and pulled it off breaking the piece that held it to the car on the right front. 10 bucks most places but the plugs with the kit are supposed to keep it from drying out. So far it has held up bouncing up and down my driveway. A ten dollar gamble but you can always find a use for a dab of it if you have it around.

Re: Small Block Fan Shroud

I looked into repairing a broken tab on the fan shroud that was installed on my K10, but I discovered it was the incorrect non-4x4 version and ended up buying a correct one to replace it.

Here is a link to the repair process I was planning to use: https://www.polyvance.com/vista.php

Re: Small Block Fan Shroud

Well only the corner tab on one side is broken. The other side is cracked. So the damage is not as bad as on the guy's station wagon.
That is an interesting product -- thanks for the link -- but I'm gonna try Grumpy's Superglue/BiCarb trick first.
I did it once before when I had to fix the accidently-enlarged mounting hole on my Wiper Knob. I forgot I was driving a '68, and as darkness fell, grabbed what I thought was the Headlight switch. It came off in my hand after a hard pull. My truck was a fleet truck, all-manual, all Standard trim. The Deluxe knobs with the metal dot center are all you can get aftermarket. So I fixed my original.
One of these days, I'm gonna remodel the dash on my '71 GMC Jimmy to be all '68 looking. I already have the manual choke.

Is that an Orange Stepside in your Avatar? I'm nuts for Orange Stepsides.
