Dear Welder Series…
How can you calculate the length of the upper and lower bars so to know that your rear four link will work effectively ? I have a 1956 chevy bel air will use coilovers!

Dear Ken…
Ken, a triangulated rear 4-link is fairly forgiving if you need to change bar dimensions a bit. Our standard bar lengths will work well in your Chev.

Thanks for looking at Welder Series parts.
