CM871 to CM570 swap

[Doops22]

I bought the donor truck complete, a 99 western star, it was in a wreck. I put batteries in it and got it running before pulling it out. It ran smooth. 3 of the coils look like they’ve been replaced, and look the same as the 1 original red one. They look different than the ones on my 871. I’ll try to attach a pic. As far as I know they are 570 parts.
