Yes, but Muncies are easier and require the same floor/tunnel mod as a ST10 as the shifter is in the same spot. Muncies were standard in some HQ's so you can copy the floor mod off one of these cars for either box. Both use the same bellhousing and clutch setup too. On a HQ-mid HZ you can simply use a HT-HG 253/308 4spd bellhousing (also same as A9X with ST10). Late HZ will require a Dellow or CRS bellhousing. Either Muncie or ST10 will use a TH350 crossmember, best bet is to find a 1980-181 WB Statesman one and shorten it an inch or so on both sides. Muncie uses standard HQ 350 manual speedo cable, can't remember if ST10 is on same side, if not use a HQ-WB TH400/TH350 speedo cable. Tailshaft will be OK from the Aussie box.
