I went with the option to just modify the kit suspension for this build and it looks pretty good so far.
Here is the updated body after I used a dremel to shape the cover over the suspension.
And an image of the completed engine.
The body will be glued on so this is all you will get so see when complete.
A larger images so you can see the spring!
Tomorrow the body will get a clear coat before the red to give a very smooth surface.
Feedback welcome!
