Hi.all -first time here,and looking forward to a lot of learning about my old chevy.I bought this truck in very good shape.As i have time to work on it im running in to little problems.This is probably why i chose this project i love old trucks and a challenge.I ordered items for an oil change and general tune up.First the oil filter didn't fit(ordered from obsolete chevy parts,and jim carter)The catalogs were very specific and it should have fit.The points sent were not right ,the distributer cap was to big.I thought maybe the motor was not original.I checked block numbers and yes they are for 41 to 46 235c.i.Last resort i took the points to advanced auto we looked through their pics on the computer.I will find out tomorrow but the points for 46 to 48 look like the right 1's.Is this common in getting part's for the old trucks?
