then came major snag # 1! DOH!!!!
the original plan to use plastic batt holders didn't work out as the bent frame rails of the chassis were in the way so i could not slide the batt in or out of the batt holder^&$^%&^($%#%$*.......

so chucked some 8mm alu rod in the lathe and ..
tadah!!!
not the pettiest but it works...:o
