Good product but no instructions Rated by Paul on March 21, 2019
Summary: Purchased this for my '68 Mustang coupe. All pieces fit perfectly. Everything seems to be of decent quality. There were absolutely no install instructions with the kit. I searched online and found a few different sets of instructions, but they were not for this exact kit, and they were a bit vague on a few details that I felt were critical.
Yes, I recommend this product.
