Please advise

I bought a "bucket boom" sitting on a 1982 Ford C800 (not roadworthy). I'm looking to have the Hi-Ranger tower mounted on a chassis that is under CDL.

I'm having a "heck of a time" locating a Cabover chassis with a Front GAWR_7,000-7,500 LBS / Rear GAWR_15,000 LBS. I need a CA around 108" (no less than 102"); a CF of about 200"; a WB of 160"; an AF of about 70"; an OAL of about 24'; hydraulic brakes, power steering and PTO.

I've spent "hours" on the Web checking every manufactured product. Either the GVW is too low or high; the WB is too long; etc..etc.

Please guide me.

Thank you in advance.
