Hi guys I got my 71 Olds today and it,s a great kit.I think it,s as close to a modelhaus kit as you can come.I looked up the wheelbaseand in 71 Olds used 124" I tryed the 70 Impala the 70 Buick and 66 Buick and the 70 Pontiac bonny and so far they all drop right in.The Impala has the best detale.The Olds has the firewall molded right in and the detale on the hole kit is great the only thing is the glass but I think I can work that out.Rick C.
