I was in the same situation on my used L35. Some dealers sold the L35 less the 3 PH stuff even though it was supposed to come standard. After looking on e-bay for a couple weeks I gave up. I finally found a guy with a new L39 & asked him if he would sell the arms & ect since he never took the BH off. He didn't even realize he had the 3 point stuff on the tractor. He took $250 cash. The links are stored on the LH subframe & the arms are under the BH between the wheels. You will need a cresent wrench to take the retainer bar off the arms. They fit my L35 perfectly & after putting them on I doubt an aftermarket set would work. As you know everything is packed in close on these things. Good luck.
