Ed, my Rallye Green car was similar to yours in that it's X11 style trim, vinyl top, 4 spd, but also had power steering, Z23 interior and guages. It was sold at Yenko, but there's no specific breakout for options or accessories listed on the Yenko Invoice or Order Form. The net price was $4550.00, tax $216, tag/title $8 for a drive out of $4774.00
I can email you a copy of the invoice if you want.
