Flywheel for 318 and NP435

It's part# 2843211 and fits many applications, including D-series pickups with the 435 and 445 NP transmissions starting in 1969 and going through at least the 1987 model year (I don't have the info for later models at the moment). The same flywheel was also used behind the '67-9 B and C-bodies with a 383 and 440.
