Yes, mine is much the same. Starter not original, water pump and clutch fan not original. But original carb, alternator, distributor, power steering setup; have original fuel pump; Still has the original chrome ball on Hurst shifter, although most of the Chrome is gone.
when I first got the car, I was looking for the 90 degree rubber elbow that goes from the air cleaner to the LH valve cover. (previous owner had installed "racing air cleaner") Man at the parts store said "Good Luck Charlie"; Went home and found it in the trunk. It's been a lot of fun for a long time!!
Jimmy, the coolant pump is the one of the few parts on my car (besides maintenance items) that had been replaced when I purchased it in 1980.
