I would think the 348/409 shroud for 61 would be pretty much the same, I am happy to be corrected.
62 - 64 409 shrouds would be consistent as no 348's were offered, there are differences between (I believe) the 62/63 shrouds as against the 64 shroud.
others might chime in, but I also thought the 59-61 348 shrouds were similar.
