Alright folks, here are some rough mock up pictures. I will have the clearance the chassis for the spur but not much, maybe 1/8'' to 3/16'' on either side would be plenty.
First order of business though is to install the rear diff as soon as possible so I can move on to positioning the center diff where I can use some of the dogbone shafts I current have. If I can only position the center diff where I can only use 1 of the dog bones I have, I will have to buy an RCM Revo shaft coupler adapter for use with 1/8 diffs and make a custom length rear shaft with a Revo shaft. And I may even do that for the front center since I will be running a bigger pinion on the motor, which will move it upward, which in turn will allow me to use a front center Revo shaft.
Anyway, I'll figure it out when I get to that point. Once I get everything I order from Ebay, I'll get it all together, rob the the 23mm adapters off my E-Maxx and install them on this truck and put on my 40 series crime fighters and see how it looks as a rolller! That will be the first time in about 4 years that it will be a roller. I've had the truck for about 6 years (it's an original .21 Monster GT), ran it for 2 years, then it sat in my garage for the past 4 years and I've been robbing parts off of it for other stuff.
Now on to the good part, pictures!
Again, these are just rough mock up pictures, it will look better alot better as the project continues.
