this was taken from mig a few month back hope it helps...it is soon to be in the tutorials an faqs section
first you get your donor beam..mine came from the K reg cavy SRI i got my
2.0 16v from. Then you unbolt the hubs, that lets you get at the spacer plate
that is welded onto the beam..and has the holes with the hub to fit.
Carefully grind off the beads of weld from each side of the plate, try not
to buff into the plate as you need it
then get your corsa beam, i got another one form the scrappy
for £20 so as to keep my car on the road, and you unbolt the drum
hub and remove the spacer plates from the beam, taking care not
to grind into the beam this time. Chuck the small corsa plates and offer
up the cavy plates. You will see little difference right away. Clamp the
plate onto the beam, i set it so that the plate was level with the top edge
of the beam and the hole in the middle centred. You have to be very accurate
to get both sides the same as this affects where the wheels will sit in your
arches but dont worry to much as there not a lot of room on the beam surface
, so you cant go far wrong.
Then weld the plates onto the beam. The hubs bolt through this plate so the
welding doesnt have to be ship building standard. But i like everything to
be strong so i had a mate seam weld around the plates.
The I drilled out the beam at the cavy spacings in the plate just welded
on and opened out the centre hole to suit the abs type hub that later cavy's
and astra's have. (leave this as it is if you dont have ABS) early mk2 GTE's
dont have the lump sticking out the back so will just bolt straight on
(they also have bolt through the hub .. not studs and nuts like the cavy)
Then i bolted on the hub, the top 2 nuts will need a bit of relieving cos they
are very close to the edge of the beam now (i went to local fastner suppliers
and managed to pick up 2 bolts with an allen key head that where the same thread
and size as the standard ones, this made life alot easier as the heads on the bolts
where alot slimmer and also was able to use an allen key to bolt them up
therefore no relieving required)
this took me about 4 hours to do, the metal is quite heavy so you need a good
drill with with sharp bits, a grinder, and access to a welder
next is to sort the handbreak cables, you can use the standard main corsa one
and an early (i used a 1987) short nova cable. Run the Main cable from the handbreak
to the drivers side rear disk and use the short nova cable from the passenger rear
disk to meet up with the main cable on the adjuster bar...
