Greetings Guys; I ordered the car without a radio & of course I have the delete panel in a box packed away. So you're asking me to remember 38+ years ago & I think I do. First I dropped it off at Zeibart on the way home (Pro applied). Then the JPS MOMO steering wheel, radio (2nd & present one 1988) nearly useless now days. Then the fall of 79 I installed the Recaro seats (recovered 2009). Then in the spring of 80 I purchased the wheels & chromed the GM engine brackets. Ya all heard the ole' adage "If it don't go Chrome it". Headers the next year, Hookers of course & at the time they may of been the only header available. Mid length w/Y pipe back to the Test Tube. As the cats of the day always needed testing 24/7. And we found out they ate about 10-15 HP (?) So the solution was to test forever! Next (82-83) the cam, intake & true dual exhaust, the results were Dismal. Ya just can't make any HP out of a 8.5 squeezer. By 85 I was discussed with the 350 LM-1 & built the first 406. The rest of the story is over on the 9C1 post, get a cup of coffee. Ole' Bob.
