130886, 420A Eclipse Engine Rebuild Posted by charlieshobbies, Dec-31-69 06:00 PM
I am currently under going rebuilding a 420A engine and I am having a hard time finding the bolts that fit in the top threads. The 2 bottom ones are straight through with no threads and the tops have threads. A 10mm goes right through and I tried 3 different types of 12mm and they do not fit. I also tried standard and no luck.
Please help me find out this simple yet so complicated problem.
