Mating a TKO gearbox to RV8

[macdeb]

Quick update; Got modded propshaft back from 'Dave Mac' today, looks a top-job and only took two days. Quality outfit who delivered what they said they could and will definitely use again. Unlike some mentioned earlier

[macdeb]

Modified bellhousing with box attached.

New TKO600 with mid-shifter fitted, next to old T5
Modified old T5 gearbox mount to take TKO 600 so as to use existing chassis mounts.
modified to sit 22mm forward to get exact same gearstick position
Modified prop-shaft.

List for any considering it;
TKO 600 gearbox with a FORD input shaft [it's the correct length]
Mid-shifter kit for above if not already fitted. [normally come with rear shifter]
Output yoke for above.
Suitable release bearing.
Propshaft modified to accept new output yoke [best measure length required when fitted in the car].
Modified bellhousing as previous.
Crank' Spigot bearing needs to have id machined out to suit larger diameter input shaft.
Input shaft carrier has to be machined back if fitting twin plate clutch.
If using external slave, Release bearing carrier id machined out to suit larger input shaft carrier, end machined to take new release bearing, and shortened at front by around 13mm [best take measurements first] if fitting twin plate clutch. [takes all of 10 mins on lathe]
Modify gearstick so by moving it forward by 22mm if exact standard position required [it will fit through hole in tunnel without but makes better job and only takes about 30 mins but best measure your own first in case]
Modify existing gearbox mount [as pictured] so as to use same mounting points on chassis.
If fitting twin plate clutch, the flywheel will need re-drilling/rebalanced to accept. I went for purpose made steel flywheel as it was an easier/better job. I had that lightened and balanced also.

I will no doubt edit

Hope it helps, PM if anyone wishes.

Mac,

I've installed a hydraulic puller slave, in the position that the clutch cable would ordinarily occupy.

Best regards,
Bernard.

Hi Bernard, hope you're well but,,

pleased to have found this really interesting thread as I'm close to pulling the trigger on the TKO 600 package from Roadcraft

Question is what sort of exhaust mods are needed to clear the gearbox please? I presume something will need to be done as it's tight already

I have a 1992 Griffith (LT77 gearbox)

Currently engine and 'box are out so this would be an ideal opportunity to upgrade

cheers

Maybe a bit late in answering, apologies. But an ever so slight indentation to exhaust around the lower gearbox/bellhousing bolt area. Good luck and good choice.
