What gearbox is this?

[HK1837]

Torana V8 rat-trap relies on the bellhousing rear bolts to attach, yours looks like a Dellow so has longer bolts and will not fit without modification.

I just looked again and you can see where the HX style rat-trap has been modded to suit the longer bolts. That Holden setup should work in your Torana with the Torana pedal and cable but may not clear the extractors.
