So I finally got the mufflers in the mail yesterday and got to the shop today. The shop is charging me 225 to mount and weld everything, no clamps. The owner and his wife are super nice and deal with customs all the time. He has pictures of his two 68 Camaro and 69 Camaro show cars all over the shop. I have my camera with me so I will upload the video tonight of the before and after. I'll give my review of their service when it's complete.
