7045228 should have:

Primary Jet - 71
Primary rod - 47K
Sec rod - DL
Sec hanger - P

Since your jets aren't marked, I would seek out some that are to be sure. Lots of rebuilders put in generic parts in that oh so critical area.

You're .002 off. I wouldn't worry about it. If you want to be **** you could get them back to stock, but you won't notice any difference.
