Correct. I just rebuilt front/rear suspension three wks ago on my ‘62 Belair. Yep, had rear backing plates wrong.........changed them out and ebrake cable fit perfect. Finished front rebuild. Brake line didn’t fit(?). Switched them out......... perfect. I learn the hard way!!!!!
Funny when things go together correctly, things just line-up and function perfectly.
Front spindle same left or right from 59-62 part number 3756789. 58 is by itself of course p/n 3749438. The steering arm that your tie rod bolts to is tirckier 58 by itself L&R different part numbers, 59 by itself L&R different part numbers 60-62 L&R different part numbers. If you can locate donor hubs from 61-67 I would highly recommend switching to them and the tapered roller bearings are MUCH better design and safer then the ball bearing design. Be sure to get the big washer with the tang on it from the donor as they are different size.
