No offset linked needed & chain would be way too long!! . Assemble connected chain on both sprockets then slide both sprockets on hex shafts simultaneously. BTDT several times with new chain. At some point JD even offered that chain connected with no master link coupler. There's also a tool one can use to squeeze links together so coupler link can be installed BUT space is very limited for installing that short chain. Zip tie can also be utilized to pull chain together to aid in installation of coupler link then cut zip tie..
