Really? I saw an ad that said he had a track for a 1980 to 1989 340. I was about to buy it but I looked up the part number on it first and it was for a 1980 440. I told him that and he said ya it will fit your 340 too.
you might want to look at ait as the ss track is no longer availible and they tell you to mount the skid further ahead and use the et340 track on it. bro looked into it when he was given a 1980 ss440 as the track was trashed. we decided to 121" it and put a proaction in it instead.
