This shot is from NCSURF (vince) on the Samba thread where he is restoring a metalflake manx. See his thread under Ricks Restoration...very informative for restorations.

Hi Mike. Please see the attached shots. This is a signature manx...I think it is Luckycharms car...cannot remember exactly. There were not many of these emerald Green Signatures made.
Regardless, look in the spare tire sump...you can JUST make out a little bumped area in the left portion of the sump. That is for header clearance as Nelson mentioned. The second shot is a manx in primer...this shot clearly shows the bumped area in the sump. Note that this is a circa 1969 body..no tag but with the big license bumpout.
