UPDATED 3/2020: Bronco RTR stretch to WB4 servo question

[1esotericguy]

Hi Guys. Dusting off my early Bronco RTR. Going to mod it to take a proline C10 body.

Already read all the threads on stretching to WB4. Bought the spacers and the longer threaded rods etc.

Question: will I be forced to change my servo mounting to front to back when I go to WB4? Or can I leave it as is (mounted across chassis)?

I’d rather leave it as is just to keep this change simple. Hoping I don’t need to wait for any new steering linkage parts to get this done.

Servo positioning was different in the shorter wheel based versions so the floating battery tray had clearance. I run 2 K5's, one front to back and the other side to side with no noticable difference.

OP here. Thanks. Just finished doing it.
Learned two things maybe not mentioned in the thread yet:

A. For RTR WB1 to WB4 = the rear drive shaft will be too short when complete. For the RTR Bronco, I got the short/short driveshaft setup from the factory. Need to order the short/long replacement set. VTR232079.

B. Never noticed, but my rear upper links were 61mm from the factory. Pretty funny. Wrong all this time. All 4 links are supposed to be 66mm in the rear and my uppers were not. This is on a really early Bronco RTR. Here’s a pic of the four links laid out after removal:

Very good points. Here is a pretty clear explanation of link lengths for the different wheel bases.

Good point on the driveshaft comment as that is definitely going to need to be addressed.

Here’s some pics for reference if anyone else is wondering about this Bronco RTR to WB4 change. That’s the stock RTR body on the now stretched WB4 chassis:

OP here. Updating this in March of 2020.

It took a global pandemic, but I finally painted this body. I used liquid mask for the first time. I like this stuff, but it’s pretty space constrained in this shell. In retrospect, I needed a short and stubby xacto handle to pull these lines. Normal handle didn’t fit, so my lines are pretty bad. Fun body though.

Looking good in red/white, love the older bodies!

Nice day to drop in some real wood paneling in the bed:

Added some lacquer to the boards
