Also can anyone tell me the correct backspacing of the 15x8 wheel ? I would like to run 275's on my 78 and need to order wheels in an 8lug pattern but i need the BS dimension.

email me direct let me know what you have....

I have two sets of left and right sides. They are good drivers condition. What is most important is the backing plate that goes inside the door. It sandwiches the mirror and truck door sheet metal. I have the backing plates, original screws and mirrors. I want $50.00 per set(both complete left and right sides) with shipping within the U.S.A. I can email some photos. I will pick the best set. Also I will send with the mirrors the mounting measurements/template for door holes…… For the wheels; 15x8x275, eight lug Dodge?. Have you considered going to 16” rims? The Dodge truck has a back space from 5.5 to 6.5 in later model versions. Another words the tire/ wheel combo sits inside the fender. All aftermarket wheels are from 3.5 to 4.5 back space. If these rims are mounted on a Dodge Truck, the tire wheel combo sticks out of the wheel well about 1.5” to 2.5". I have eight 16”X8” 8 lug Factory Dodge Truck polished aluminum rims. With lug nuts and hub caps. They came off my 2001-2500 that was stolen. One set with no tires, the other set has BF Goodrich All Terrain 285 x16 tires with about 50 to 75% tread left. I will throw in the stock steel rim that’s never been on the ground for your fifth tire with the correct off set……. Let me know by email. dynamodave@att. Dave West
