Hey Paul, You should have received a e-brake boot. Should be the same one as the roadster.

Also just FYI, Although I guess it may be too late.....
I have this front accessory set up on a pickup here with hood and side panels and fits just fine. LSXM-WRAPTOR-ACO from CVF , this is what I will be ordering for my pickup.

Its about $1000 cheaper than the vintage air unit.
