I just received delivery of my long awaited purchase of a 356 from vintage motors of Calif. The car is awesome and the finish is great. Took her out this weekend for her first 140 miles. Only one problem, I am having the hardest time getting into reverse. The first day it seem to go in reverse, no problem, then as I was trying to back up at the gas pump, I could not get reverse. I have been averaging 5 to 10 tries each time I go for reverse. Its the type where you pull up then over and down. Any ideas or suggestions to this problem?
