Finally bit the bullet and got it done.
Went with the long tube coated hedmans, flowmaster 40's.
I thought I was going to hate the sound at cruise, but it sounds good. As for the tips, I went with the ovals, and not spread too far.
When talking with the guy at the shop, I have known him for a little while, he restyores classic trucks and cars, he has had several of these trucks, and assured me I would be happy with the long tubes, I expressed concerns about ground clearance, he said not to worry. I have been driving it for 2 days everywhere around town, no problems yet. If I do start bottoming out, I guess we will go with a shorty or 3/4 length. The only thing I don't like is the long tubes are a little low, but I do have about 5" clearance, and they did not put my a/c -alt support brackets back on, which I did not even notice until taking these pics. Have to deal with that this week.
I know, I need to get some new plug wires...soon.
