Parts brand reviews

So I think I have narrowed my search for engine component parts down to either Costex (CTP), Union Tractor or Korpan Tractor. Korpan i think is going to be the cheapest by quite a margin....but I cant really find any reviews from people that have used their parts. They were recommended to me by two different people on facebook. Costex seems to have pretty good reviews and my old man has used Union in the past and has had good luck. Does anyone know of good or bad experiences with any of these three outfits ? I just cant justify 12k for parts from cat for an inframe on this old D318 for a farm cat, imo thats crazy.

thanks for the help guys, this forum has turned out to be a pretty good source of information, im glad that i subscribed.

Hi Landon,
I can't offer an opinion on the engine parts, but I'm really pleased that you are getting good value from your membership of ACMOC.
