Info for anybody struggling with a direct mount flange to eliminate the "donut" on the TR6060 gearbox.
I found these billet flanges to suit the TR6060 Tri-Flange from Sonnax distributed by The Drive Shaft Shop driveshaftshop.com
TL35-ALFY-01, US$179
They positively locate over the spigot that protrudes on both the gearbox and VE commodore diffs for a centre alignment.
They suit a standard 1350 Spec Universal Joint Bearing.
They eliminate the need for T56 outputshaft conversion to TR6060 boxes or removal of the spigot on the VE diffs.
Cheers from Dave
