I just installed all these on my 07 this morning, plus the new style trigger w/OT...
Very sweet upgrade, and very easy to do... the only issue I had was the hammer strut pin was a wee bit of a pain to get started (at home without proper equipment) but a little soaking at 300f for the hammer and life got easier.
I did stone/polish the trigger bar and hammer strut, but everything else was left as is.
Used the gold hammer spring for my application...
Anxious to see what additions he makes to his posting... might have to go back in but geeze is it sweet
grabs popcorn and more ammo
Edit: Measured trigger pull tonight using Lyman digital gauge
SA: 3 lb
DA: 7lb 10oz
IMHO, that's pretty dang good for plug and play parts installed sitting at the kitchen table :-)
