Mysterious #71 K&K Daytona wheelhouse "covers" - what are they for?

20" x 2" lead bar weighs 25.8 pounds.  So two bars are 51 pounds. 

50 additional pounds is certainly worthwhile to carry right in front of the left rear wheel!

The COG #6 Charger 500 (1969 Riverside 500) has a similar arrangement.   So it is not strictly unique to the K & K.       The ones on the COG car appear that you could remove one bolt and pivot the covers out of the way.

Were both cars Nichels chassis?  If so this might be a common trait.

Nichels built DC-93 (the 88) was built for speedway use and does not have any "weight tubes".

When Don White owned the car, he put the battery behind the left rear wheel, as was the practice when there was not a rule against it. In Nascar, the rule at the time was "engine compartment", so it was tucked behind the left front wheel.
Eons ago, when I was a kid, I moved the Grp. 27 from the stock location to the right rear in the trunk of my Charger.
Yes, you could tell the difference in handling. It was an estimated 1% change in front/rear weight bias.

Some guys would slide ballast into the rocker panel itself.
