Doug - just got home after a 3+ week trip and say your package. Will open it and drop you a line today. Thanks!
Kevin - I only drove her on/off the trailer. Loading a race car on a Uhaul, in the rain, with hard slicks on the all four tires in the middle of nowhere is a treat, let me tell you. At one point on my second attempt the car started to spin it's rear wheels and almost skidded sideways off the trailer. Good times...
I did have another freak out moment with her last night however - I got the car loaded and home OK but when I was going to park her and actually turned the wheel, rather than just driving her straight on/off the trailer, there was a pretty severe bucking from the rear wheels.
I've never driven a car with a locked/welded differential, and it's been widely (two knowledgeable friends and the prior owner) suggested that as a race car that is what is going on here. I don't have a good history on her, so short of pulling things off her I don't have an easy way of confirming this unless putting her wheels in the air and seeing how they spin would be confirmation.
Ideas?
