If you have a good steady bench drill with a good table and clamps, with a slow spindle speed, and with carefull work, it should workout ok.
Put a 8mm drill in the drill chuck, line it up in the 8mm drilled hole in the rotor, and clamp the rotor.
Get a 10mm drill and grind a 45 degree angle on the outer cutting edge, so that the drill works like a reamer, and is not drilling a blind hole, but just drilling a bit bigger on the edges.
Run the drill about 200 revs per minute and see how it cuts.
If ok, do next hole by lining up hole with 8mm drill and then putting in 10mm drill and drilling.
Wear safety glasses and clamp work tight, Colin.

it depends if you have the spacers in between the axle and the discs like an early car, or no spacers like a late car.

no spacers you should be right, if there are spacers the actual offset of the mounting part on the disc is different, so might put that bit extra load on the driveshaft

Hey Sportiva,

We have x3 seperate listings for rear discs for the Alfetta/GTV/75 series cars.
The early Alfetta with M10 holes
Later Alfetta/75 twin spark M8 holes
GTV6/75/90 V6 with M10 holes

All x3 have different offsets and different OE#

So if you were sent ones with M8 holes, then they were for 4cyl cars and run different offset to the V6.
