My problem: I have a 1977 Ford F-100 with a new crate 350 and refurbished TH400. Currently it is a three speed on the column (boring! ). I am having issues with the engine dying when shifted from Park to Reverse or Drive (But it runs fine in Park or once in Reverse or Drive!). I am not sure what is causing this, but I was hoping a new floor shifter may help and would look better.

My question: How difficult of a job is this going to be? And what would be the best aftermarket shifter for this application? (I like the look of the long nostalgic shifters and can't see how a short shifter would work in a truck).
