This cool insulator seems to be a very one of a kind piece. Note the inner skirt is perfectly even with the tips of the drips, and if this were the SB EID, the inner skirt would be about 1/4" longer and the insulator would sit rather on the inner skirt than the SB.Has anyone seen another SDP extended inner skirt Hemi 40 like this? Please contact me if you have any info on this variation. I have placed a regular SDP version next to the extended skirt for comparison.
