Ignition Switch
Review by Rich on 29 Oct 2024 review stating Ignition Switch
I ordered the ignition switch and cylinder with keys. The opgi catalog offered only one ignition switch and an option for two different cylinders with keys. All the parts were applicable for a 65 Skylark. The cylinder I picked won’t work with this switch. I made the call and spoke with a technician. If the picture showed the end of the cylinder it would be more accurate. With that said the tech team said they would send me the correct cylinder at no cost to me. It’s one major reason I continue to purchase my parts from OPGI. Thanks and keep up the Great Work!

Review by Jeffrey on 18 Oct 2024 review stating Wiper arm pin
Although I ordered this Pin for the Wiper Arm Assembly, as the description of the assembly stated I would have to order one, the assembly came with this pin already installed. I'll keep the pin just in case it's ever needed.

Rear sway bar
Review by Wayne on 19 Sep 2024 review stating Rear sway bar
I recently bought and installed a rear sway bar for my 1968 buick Skykark GS 400 and it was one of the best decions I've ever ever made. My car handles and drives so much better.. shipping was fast and the price was better than the competition, especially considering the part was not a cheap knock off.. I also installed a new pair of lower contol arms as well. OPGI is totally the way to go!!!
