The 742 is a rare bird in these parts. since the last year for factory install for the 742 was the 68 model year I'd say finding a 742 FACTORY installed in a 69 would be very rare , 70 not al all . 489 and 741's for 69 and up . of course someone will chime in saying they have a 70 wit ha factory installed 742

The guy that ordered it was a friend of Lee Iacocca who gave a COPO order to ship it over to Chevy.. Very rare.. I have paperwork from GG verifying its a "one of none"..... LOL
