New 3905 Chassis steering questions...

So have everything bolted up to the new FLM 3905 Alum chassis... but the steering isn't a straight bolt on... not terribly disappointed, but what steering is supposed to work with this chassis?

The stock steering doesn't sit in the machined recess and is too tall... sits below where the skid pad would attach...

Any ideas? This is my first FLM Chassis build... am I missing something?

Also had to grind a bit of the hybrid bulk to get the upper Flex Tec arm to fit...

Otherwise, very impressed...
