Hello, I have a 71 Riviera with a broken down 350 GS 1970 inside it, but there is still a TH400 transmission behind it... Now i want to restore it back to a 1970 GS 455... For as far as i can see they have only placed 2 metal plates under the 350's mounting points... Does anyone know if they also had to do some adjustments to the TH400? Because i bought the car like this... With a running engine ofcourse... Kind reagrds, Michiel, The Netherlands
