1971 Duster 727A Transmission is Missing Dust Shield

My car was formerly a race car, which I suspect is the reason why there is no dust shield on the lower half of the bellhousing - see attached pix of under my car and of an example dust shield.

My car is strictly for street use now, and my concern is road debris getting into the bellhousing, ring gear, etc. Is my concern justified and should I install a dust shield? Opinions welcome - thanks FABO nation. Dave
