Bryan,

As said, here are the parts I ordered to refresh and slightly upgrade a used L3:
4222 - CRC - Complete Large Ring Diff - Silver (there are others colors)

As mine is used:
1972 - Robinson - Spur Gear 48DP 72T - Was thinking in ordering a Kimbrough 48DP 76T - the one from stock but not available @ LHS . Is that a "good" choice knowing I shall start with 540 or so?
4520 - Associated - 12LC/L3/L4 Symmetrical T -bar, .063" thick - spare
1610 - Protoform - Speed 12 B
2325 - Jaco - Jaco 1/12 Medium Firm Low 3-Hole Wheel 1.40" Purple
2345 - Jaco - Jaco 1/12 Wheel/Tire Rear Gray


After, there is some items I purchase because I don't them at all, re-entering RC after a will:
6591 - Associated - Associated Diff Lube, 4cc
6588 - Associated - Black Grease

I did not buy any lower motor mount or so, the first step is to learn how things works!

Any comment?
