Thank you all for the help. I had a 70's 454 with a dip stick that fits, and is too long, I guess all the chev ones will fit, maybe not stock, but will do the job, with the correct markings and length. I have 3, 235's and no one piece dipsticks. The truck came with a coat hanger wire for a dipstick.
Shop manual? I have 55, 57, and 3, 58's and 59 supplement, I've had them for a long time will that work?
Dealer stocking parts? Sorry I didn't know they still had 1950's 235 parts, ignorant me.
