That website has one minor incorrect detail. The third type of lower A-arm with the oval bushing began in 1970 and is not correct for 66-69 cars. Ovals were used on 70-72 non-SS models.
Also, I can't remember exactly, but I think he has the early/late bushing diameters mixed up as well. I think the small bushings were early, and large bushings were later... been a while since I messed with this stuff.
66 was the transition year for the bushing diameters so either may be correct depending on build date and which plant... not sure if anyone has ever looked into it any further than that to document when the switch occurred at each plant.
The bushings I took out of my 66 which was a 12E build and original, I think, have OD of 1.900" and 1.660" respectively. Just now locking at the original bushings, Interesting is that the rear or larger bushing has a double steel inside sleeve where the smaller or front bushing has a single sleeve inside cylinder. I will have to look at the Nov of 65 parts car I have out in the back forty/

Mitch the arms I have do not have the oval bushings they are round. I have a set of uppers also if you want them to be able to do it all. Let me know.
Chris, I'll take them !! I will get them powder coated and all built up for install this winter. I will get the take-outs back to you. One of the lowers was changed and is the oval style, if that matters to you.
Derek, you are correct that the larger diameter rear bushing came out later. My May built SS has one of each and I had to special order the other size when I installed the urethane bushings that came in a kit. The kits weren't offered with one of each...
Another interesting tidbit is the frames. My May car has the '67 style "shovel nose" front crossmember and so does this 11A built Malibu. I was always under the impression that the changeover occurred much later in the run than October. Maybe because it's a California car ?
It is a parts book page for 67 and earlier bushings. It shows the second design happened in 66. Kind of hard to read; it show the smaller bushings starting sometime in the 64 and changing sometime in the 66 model years?
My two cars are 11B and 12 E build, Kansas and Flint respectively. Frame date stamps precede build dates. They have the open extension on the front the the crossmember thinking you meant a closed solid piece by the term shovel Mitch. I also thought there was a difference in the Z bar mounting bracket.

Dashboard probably knows how to decode the driveshaft stripes, as he did it on his Elky and repainted them.
I think I did at one time, my research is packed away in a box somewhere; Jon H packed it and I haven’t gotten those boxes yet.
The drive shaft is listed on the Build Sheet or perhaps Broadcast Sheet for 66 so the line worker knew which shaft too grab.
I think in 66 there were both body and chassis broadcast sheets. The body one used by Fisher as they assembled the body and the chassis one by Chevy as they built the chassis.
Nice project Mitch, that would be a sweet ride with a sassy small block and a four speed.
