Those of you that have been following my build [new toy for this old boy ] see that I am putting a 383 into a 68 Barracuda, Yesterday when I was bolting the tork converter in I notice the steering was hitting the oil pan, no right turn Over the years I have read that if you use oil pan 187 with the dimple on the right side. you should have clearance for idler arm and not have to customize a pan to fit.
