Need to find a truck wrecking yard for CAT parts

Can anybody recommend a good used heavy truck salvage yard? Trying to find these parts but the few wrecking yards that have what I need are asking more than CAT is for brand new parts.

I'm searching for a set of valve cover spacers for a 3406B CAT. 7E0329

Also in need of the spacer(jake brake housing).

 

Thanks!

 

Hey stranger!

Another day, another round of broken stuff...LOL

 

LOL! This time it was our(FORMER) mechanic, long story.

Funny you mention Volvo's...The boss bought an old one and the trans went out, had to limp it along with only 7th&8th. Penske sent us one, real sluggish to crank but "certified road ready" and died on the HWY. They rented us a truck with a blown head gasket, antifreeze visibly weeping between block and head on #5. "Dedication at every turn."

 

Yeah, wouldn't want that. I know somebody who'd been thru that. Pucker factor 10000
