Undercarriage parts common to a 450 and a 550 dozer?

[emkothe]

I am trying to figure out what, if any, parts are common between a 450 and 550 undercarriage? I could post some part numbers from my 550 manual if someone has a manual from a 450 to compare to. I found a 450 locally being parted out.

I need all the wear parts, but am also missing the front shields and the inner and outer shields on the lower rollers. I presume these are important, but missing on my machine.

Bottom track parts on 450-C serial # 216303 and up the same as 550 as far as I know

OK here are the PNs from the 550 manual that are in question. The top list are wear parts, the next 2 are parts that are missing. Last is the frame rails. I think I can straighten them, but if I can buy straight ones cheap I would.

Just trying to avoid a long drive if they are not going to fit.

Any help appreciated.
