87 na wiring harness..

[7Mpowered87]

i'm buying an 87 na this or next week. it has no rust on body and about 50k on engine and trans.. the only catch is who ever had it before my friend removed the cd player/sterio and left wires open, which lead to part of the harness shorting out..the current owner had bought another harness but it's a "right hand drive" harness..is it that much of a hassle to use the Rhd harness or am i better off looking for another Lhd harness??
