CL713 Frame replacement

[Mack713]

Hello, 

I have a 99 CL 713 Mack triaxle double frame that is starting to show its age with rust between the frame rails and don't want to get rid of the truck so I would like to replace the frame by getting another one to completely strip down and build back new. I know there is a company that can make new straight rails however I would prefer to now cut my frame. 

Is there anyone here that knows someone with old frames laying around or what frame models match up with a 99 CL713

I don't know what would match to your truck, but I did notice that Mack actually shows to have your frame rails available. I'd definitely try to find some good rails to use elsewhere, but at least you have a worst case option. I wonder if an early CH or late RW would have similar frames?

CH has different chassis, straight rails. Same style went further to CX and some Granites I belive.

CL frame rails are interchangeable with 2nd generation RW Superliner and MH Ultraliner. If I'm not wrong there were no Ultraliners with tall 700 series rails, at least there were no MH700 series in the production line. RW rails were made both 600 (1/4 thick) and 700 (3/8) but those may have shorter front end to be used in CL since RW in standard configuration doesn't have offset front bumper.

And one more tip. I once contacted Global Truck Traders guys in MA and they had quite good and long used CL frame. I'm afraid 3 or so years passed since that but may be worth making a call.
