I have original bench seats in my '70 Chevelle which have a tear in one of the seams. I brought it to an upholstery shop who said to leave it as there is no way to fix it if I wanted to keep it original. Pulling the two sides wouldn't work and just stretch the material. As it feels like the tear gets worse every time I sit in the drivers seat, I thought I would check to see if anyone has any thoughts/ideas on fixing it or avoiding further tears? Any advice is appreciated!
