underbody for Baldre ????

[mr. ed]

Hi folks, I have a baldre body on my yokomo buggy creation (built around a YR-4 chassis).
The bulge for the moter ont hte baldre body sits exactly right for the leads of the stick pack running across on my car. So I love it.
But I'm too scared to run the buggy without underbody (the rear bulkhead is a gaping hole ready to eat anything).

Can anybody tell me if the trf501 underbody will fit, or I got another option?
