Ask a Question-
Can you help me with the correct fasteners needed! I would like to get new ones
We don't carry those fasteners currently, but are looking into stocking them. We'll let you know once we have them, but feel free to follow up with us if you haven't heard back by the end of the week. Thanks for the question!

I noticed the replacement undercover does not come with the insulation pad, a part which has unfortunately been discontinued. Do you know if this part is needed and I should go through the trouble of salvaging the pad from my old undercover?
I would run it if you can. Most people don't have much of a choice as these original units are beyond saving. I haven't heard of any difficulty run these without the insulation. Still there are generic options out there if you need the protection. Thanks
