Common questions
How do I know it fits my truck?
This part is listed for 1973–1987 Chevy and GMC Blazer, C10, C1500, C20, C2500, C30 and others. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
What if it is not right for the truck?
You have 30 days from delivery to request a return. The part needs to come back new, uninstalled and in its original packaging - once a part has been trimmed or welded it cannot go back. Return shipping is at your cost, and we ask that returns come by Canada Post. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
Can I install this myself?
It is designed for an at-home install. Read the fitment notes and the Installation tab on this page before you start for anything that needs drilling, trimming or welding, and where an installation guide or video exists for the part it is linked there.
