Doing my searching and getting more lost along the way I noticed there are two different 4.2 rods. Here's what I found...

258 rod
pin type .9310 , pin diameter 5.869
pin type .9212, pin diameter 5.875

242 rods are all the same
pin type .9310, pin diameter 6.127

Soooo what 258 rod should I go with here ?

:brickwall:

SO MANY QUESTIONS EVEN MORE ANSWERS

What Russ said.
Any 258 rods that come with a 0.912" pin size have probably had the small ends bushed to accept full-floating pins with aftermarket forged pistons.

You know there are medications for your head banging.....I'm just saying.
Life's too short to be as frustrated and angry as you are.
