Question A/C delete bypass pulley

Hi all, I should have done this long ago since I only ever drive this car when it is top down weather, but what is the best option for an A/C delete bypass pulley these days? Took the Camaro to work yesterday and it wouldn't start in the evening. It acted like it didn't have enough juice so I tried jumping it to no avail. I heard some bearing noise recently and assumed the alternator went out. So I took the battery home and charged it up overnight, it was down to around 30%. Took the battery back at 5am figuring if I could get it started, I could at least get it home to work on it later. Well, the battery managed to start the engine (although it was very hard starting with me having to give it some gas to get going) and smoke started pouring out of the hood. I quickly turned it off and ran to the hood to see the belt trashed and charred. So when the auto parts shops opened, I went and bought the only alternator in town and started the swap in my work's parking lot. When I got the old one out, the pulley still spun, although the bearings sounded horrible. Since it still spun, I figured that wouldn't explain the belt so I reached in and tried the other pulleys. The A/C compressor pulley did not move at all, so I assume it seized and that's why the belt died.

TL: DR A/C compressor is toast and I need to do the A/C delete but can't seem to find the 1LE GM part anywhere and have heard horror stories on the Dorman one. Any suggestions? Thanks!!

Sure, but when you have to drill out the holes so the bolts will fit, have to shim the pulley to be aligned, and still have the risk of the weak aluminum arm snapping like a twig with the slightest pressure, it goes beyond "its just a pulley". Hence my question wondering if there is a product that's actually designed for my car. When it comes down to it, I'll probably end up using the dorman, but crossing my fingers someone knows of a better option.

FWIW I have a dorman ac delete pully on a LT1 I converted to carb and used the LT 1 accessory bracket in a first gen camaro...no issue. It was a plug and play install. no drilling or shims needed...YMMV

Thanks, I'm glad to hear that, makes me feel a little better about the part! I'll be ordering one soon. My daughter's fifth birthday is in 3 weeks and all she's asked for is a ride in the Camaro without her older sister along haha.
