There are a few out there but watch out.
From the Spec to the regular kit you get shorted on the following.
#1 is NO bearings in the front wheels or rear hubs.
#2 is cheaper shocks which DONT have interior coating.These wear fast and arent as smooth.
#3 is the universal's.They are called sliders from back in the day.
The outdrives are actually plastic as well but not the racing one's some stock guys use.
Some of the parts expecially universal wise can be a PAIN to get.
Hope this helps.
