some usefull info

[GREASEMONKEY72]

well i spent most of the day changing my gear oil in my diff and cleaning the caked on dirt off the houseing and went through a few cans of brake clean spraying out the inside of the houseing but i did find out some info that some of you might find usfull stock gear for a 71 custom/10 with a 350sb/th350 combo is a 3.07 and i counted the gears but came to find out that if you look on the outer edge of the ring gear there are numbers eched in and the gear tooth amount is there and for example mine is 14:43 you can still count if you want but if not then the numbers are on the side just thought everybody might like to know that didnt already oh and by the way if you havent changed the oil since youve had you might want to cause mine was blacker than black ..haha..
