Been doing some searching. I found a couple sources for a big block A-body pitman arm but nothing on an idler arm specific to big blocks. Year One also lists the pitman arm being the same for power or manual steering. Does anyone know if perhaps a big block B-body pitman and idler arm combination might work? Also, I've found pitman arms listed as 32 and 36 splines. I would have thought they would just be one or the other. I'm still thinking the 73-up manual pitman arm, center link and a 73-up idler arm would be the way to go in my situation if somebody can confirm that it will fit on my 69 power steering box. Don't want to order them only to find they won't fit afterall.

I looked at rockauto and they show the same part number idler not matter what engine size you choose , but I take rockauto reference with a grain of salt as they list gas engine shocks for the 2nd gen Dodges with a Cummins engine.
