Mustang II suspension issue
Returning to street rodding today after a 43 year absence! Just like riding a bike, except I missed out on the whole "drop in a Mustang II suspension" thing. My '41 Lincoln street rod, delivered today, has one and it rides like a buckboard. Looking at the springs, they appear to be extremely short, which would explain the lousy ride. So I ask of all those familiar with these installations- what's the cure? And if the answer is replace the spring with a full length one, how the heck do I figure out which spring to order to keep ride height the same?
