      Hi Spits, I'm trying to do the same thing. Did you make modifications to the steering rack or is it in the stock location? I'm hitting balancer. Rachel

      Yes I did have too I guess it depends on the year you have I heard that the 75 an app has a bigger engine bay When I installed the 355 in my friends 1975 car we didn’t have to change the steering I had to move the steering rack forward to miss the balancer Which now I am going to have to add a extra steering u joints and peace to go between the two The The angle of the shaft did change slightly as well I will try to put some photos up for people to see
