Hey Pat.... nice to see you're joining the dark side....
I paid around 300ish for mine. But mine came with enough spares for a second car plus a little...
Spares to buy.... CVD's and bones..
The pro4 cvd will bend if you're running on a track. Either get some IRS tc4 plastic's on the cheap or upgrade to Ti world ed. ones. You're having the steel UJ's will be fine.
bevel gears (for the diff)
Again, these suffer in crashes... or improper shimming. A MUST buy..
Front sus. arms
and if you end up getting the brushless... then eventually you'll need diff outdrives.
FRONT SSUPENSION ARMS
let me know when you get the car..
I can sweeten the deal for you by taking the alu centre drive cups and CF shaft off ya...I have another shaft on order but you know me....
