CALLED DEXTER about the axle's and gave me a price of 521.00 per for just the axle and 739.00 for the complete set up, brakes drums etc.. plus 150.00 shipping.so we checked the backing plate and mag, drums etc on the old ones and they are really very good still. no grooves nothing so will just go for the axle for 521.00 per,'did ask about upgrading to a bigger weight capacity but they said that will than change all the mounting holes etc... so these are rated at 3007 lbs each so should be good just will not overload.
thanks for all the help,,,,,,,again, lol
