Tremec T-56 in HQ-WB

I am considering my options for a new gear box, and was considering the 6 speed in the later commodores (amongst many other vehicles) the Tremec T-56.
I am thinking of putting the 6 speed behind a 308 in my HQ Van.
Has anyone out there used a T-56 in an old holden (hopefully a HQ-WB)?
I want to know how much trouble it was?
Whether there was modifications needed to the floor pan or not?
What bell housing you used?
What Clutch you used?
and the big one- how much it cost you to buy all the bits...?

Cheers guys...

hi,
had a quote from Tremec for that conversion, full kit is $5200 + $400 for them to fit if required, not in position to do it right now but well worth the money for smooth ride and really good economy on the highway.

do it do it do it

Can't comment on actually fitting the T-56, On advice I went the TKO 600. More then sufficient for the old Hque.Very happy with it.
Used a Mcleod street twin plate clutch and hydraulic clutch kit.I used CRS for the bell hsg.

Try Castlemaine auto electrics, I think they have a kit, they have al the stuff for the LS1's into old holdens.
At the time I was told you need to put a larger trans tunnel in for the 6 spd. Apparently the T-56 is larger then the Tremec TKO. THe TKO is (in certain areas) dimensionally based on the ole top loader...

Ive just bought a TKO600 for a HQ Coupe and was wondering if the transmission tunnel needs to be cut for clearance ?

What did you do about the speedo ?

Which shifter and stick did you use ?

Thanks

Hi, did you have to cut / modify the HQ trans tunnel to fit the TKO600?
