which one will work with what i have? can i use the one with the blue pads but use the other slipper in the other link? the 58t gear. thanks!

The blue set you've linked to is for an E-Maxx...soo that won't work. RRP does make the same kit for the 3.3 though, and they have them with a steel spur if that's what you're looking for. The spur gears between those 2 kits linked to are not interchangeable.

so you think i should get the 58t metal spur/slipper, or the blue kit for a t-maxx? i want to be able to use my rrp blue slipper back plate. here is what i got on now-

Neither of those is made to work with this back plate. You would replace that plate with the one(s) included in the kit(s).

oh ok i see. so i would be better off just getting this-

i went ahead and ordered the rrp steel 58t slipper/spur gear. that way i can use the rrp blue back plate.
