I did just receive my front and rear umper for my 72. Good quality for the price, a few imperfection, need to be finished. Not ready to paint and fit. I'm happy with them. But don't want to ship oversea, I had to ship them firts in the state then, over here. What about the weight of weld magnun pro vs centerline convo pro. I use the centerline and they are light. could the weld be lighter?
