Chevy Performance - PROFORM DIFFERENTIAL COVERS | ![]() |
Proform Chrome 10 and 12 hole differential covers. The pictures on this page were scanned from an older catalog that had only B&W photos. These parts have the same high quality chrome as all Proform GM licensed parts do. Someday these low quality pictures will be replaced when time can be set aside to take pictures of these. Note: More parts will be added as time permits. If you don’t see the Proform part you are looking for, give us a call and if we don’t have it in stock, we will try to get it for you. We have much more Proform parts in stock then we have time to put on our web site. |
