Thanks for your help guys, It is much appreciated. It does have inboard front shocks but it had a badge on back with Sierra 7 on, I've looked at lots of pics n it looks like a 3A to me, I will try to see if there are any local meets in the North east n go along to try to get advice there as well
.
I am new to this n need to find out which model have as when my wife & me are in car it seems to hit the ground quite often n I think I will have to sort the rear springs out.
