VH329 or VH330 are the two straigh rod LH style. VH327 has the single end, VH330 has the double end that goes on both sides of the pedal. VH345 is the bent rod LX style. There may be overlap each way, not sure when the ADR changed.
I sold one of these about a year ago on Ebay, ended up about $300 or so without much interest, started at $1 IIRC.
But you can get one built too. Look for one of the following and rebuild it using the front and rear rods off a 6cyl or 4cyl ones with the rear rod to suit your pedal. One of these:
VH300, VH304 or VH305 (early HK).
VH306, VH308 (? maybe Bedford)
VH311 (late HK, HT).
VH312 (HT/HG).
VH313 (Rambler Rebel, Matador)
VH314, VH315 (??)
VH316
VH317 (Little Torana)
VH320 (HT, HG)
VH321, VH322 (??)
VH324 (Little Torana)
VH331, VH332 (IHC ACCO-410)
VH333, VH334 (Ford FG Truck 250/300 series).
Some have different sized holes for the vacuum valve. The bodies and the studs at the back are the same though. You should be able to find one of the above at an older wreckers somewhere.
