My seat foams were in very good condition, so I didn't need to replace them, however - I did watch the you tube video that legendary produced, and per their instructions = even with brand new seat foams they add another inch and 1/2 or foam with spray adhesive = then trim to the contours and cut through where the listing wires embed into the foam = this step makes all the difference in the final product!!Man!! A lot of work done in short time. On the seats did you replace the foam? Or where they still in good condition?
