1966 Valiant Signet Convertible Resto

I`m going to try to piece in the carpet I cut from the new opening but I suck at seaming carpet. The idea of stitching it in sounds feesible, thanks! The Dynamat was a 9 piece kit, each 18 x 32. I found a website called www.hifisoundconnection.com that had it for $124.95, so I called Summit, they beat the price by a buck, shipping was only $9.00, and I had it in two days. Nothing against hifisound ,I just like Summit. The Dynamat should help quiet and insulate things.
