I was going to purchase a set of parking light(Side park Light) for my 71 stepside chevy and THe uy told me that they were for fleet side only so i didn't get them (I HAVE A STEPSIDE). But I was browsing the site and i ran across severl 68-72 stepside that have the same light lens i was going to get. will the parking lights work or do anyone no where i can get a set from. I seen a lot of truck using the side park lights with the chrome trimming in that divide the lens
Those were the exact one i was going to purchase. will they work on my truck? if not were can i pruchase a set like this
