I have a set of 15" X 7" Aluminum mid-80s Monte SS wheels on my 68 El Camino. They are in good shape. I'm upgrading my brakes to Baer 13" fron 12" Rear, so I'll need 17" minimum size wheels...I'll let you have them for a song and throw in ctr caps and multi-miler tires for free ($150+ shipping). Wheels list for $179 each - reconditioned at: http://www.dixiemontecarlodepot.com/subSections/s10.htm (see 'DM50002' for picture). I'll need to drive on them 'till October, but I'll sell them after that.
Cost is for all minus shipping, but I will need until October...Suggest you check out your local wrecking yard...Make sure you take your tape measure to check for a 5 x 4.75" bolt pattern - do not get universal (slotted-hole) mags...they are self-lossening - ie dangerous.
