Wiper linkage questions 67-9 cuda

This is like a rabbit hole LOL. Thanks all for replies. So like Ben was saying, your pic of the 67 with the spring confirms it Matt. Totally different bushing when comparing Vspeed and 2 spd for 67. 2770116 would PROBABLY be correct for 67(havent confirmed # in manual), as my crank arm #2770163 with white bushing is listed in 67 manual for 2 spd.
I found #2857936 stamped on one linkage arm, manual shows it as "link wiper drive" for VBL, which i understand, BUT underneath it, it states P,D,C,Y and shows different numbers for 2spd and 3spd. B=barracuda, BUT does the numbers for P,D,C,Y override the Barracuda part number? Looking at manual may help while reading my jibberish. 69 parts manual, section 23-67-79, page #23-104, pdf page #1125.
Thanks guys.....wow
