I did some work on my cutback earlier.
I eneded up putting the newer esc in the spot where the stock one was installed originally. Then adjusted my ride height after installing the upper shock mounts. I decided to be safe and order the losi upper shock mounts (LOSB2906).
Losi scte 10-T Shock Mounts (4) (From LOSB2906) SCTE-10 10T 2.0 Ten-T 810
Picked these up from ebay for $2.99 (4 pcs) plus shipping.
Here are shots of my truck so far.
