One more question, guys. In my 69 bird I installed long ago a Milodon oil system with a pan that sticks out about 1 inch from the skid plate in the K member.More recently I rebuilt the front suspension with refurbished/new parts to be as original as possible. Also installed 215-60 radials and "stock" shocks; now I would like more clearance between the oil pan and the floor, so I started cranking the adjusting bolts for the torsion bars, and here is my question: how far can that be done without messing everything? I have never seen an article that addresses this point, so maybe you have an answer. One thought is buying taller tires, 70 series, that will give me 1 more inch of clearance. Thank you.
