I found a place in Franklin Wis. called Rocore, that just built me 2 new cores for a 7C 15, same as cat 10, only $360.00 plus shipping. If anyone is interested, the phone # is 1-800-733-2673. The Rocore part # given to this core is C312910. Nice people to deal with and accualy had the blue print to build on file. New core has 3 rows of core istead of 2, so if you have to be a pureist, this won't work for you!!! Bob Stewart.

At the Cat dealer I worked for there was a radiator repair shop in the area that came around twice a week & picked up radiators, coolers etc. & they came back like new or if they needed recoring they could do it to any size radiator we sent to them.Everything was painted up too when it was returned.

SJ, I have used this shop in the past.Can't remember their name but they had two locations.They made me a rad. for a PV15, it great.
