Looking for History on 73 Socal CalClub scca 240z

[cestes]

Looking for some help finding any history on this 73 240z track car. Marked with #39 CP on hood & sides. Full side body kit/flares. At some point it had bolt on wheel arch flares, which were replaced with current flares. It also appears to have had bolt in roll bar at one time. Bolt in roll bar was replaced with full weld in cage, with gauge hole drilled in bar on pass side, but no stampings. Has fuel cell with aluminum access cover.  I got it as a roller/shell less drivetrain from Ventura. Guy I got it from said it had been sitting behind shop of one time guru z shop owner in so cal (I think he said his name was mike?). Car sat behind shop for 25 years. Has nissan comp coil overs on front & back (japanese writing) as well as imsa style sway bars, & toyota front discs. From all appearances it was raced. Gary Cook local Z guru here in Sacramento has looked at it and believes it was a race car from back in the day. Name on roof both sides says "Owner Driver" above name which is "C.F. Jones". Hoping someone might remember seeing it back in the day. New to forum, but not new to Z's. Thanks in advance for any help. Chuck
