our 72 vega has been changed over to 5 lug rotors, spindles and calipers . We do not know what they are. The numbers on the rotors are this ..3996157,,,,,,,,,,Min Thk 440,,,,,GM8,,,,,,,,G201..
the calipers are held on by press in pins,, no threads on um ???

thanks Jeff

with a lot of searching on line ,, we mite have re-drilled 4 lug rotors ?? But they need replaced, the calipers match stock vega part number ..

you might try Dave's Vega Village for stock/redrilled rotors, also consider converting to S10 front brakes.

Are they vented rotors or solid?

min thk .440" would be solid.

yes they are solid..
Dave's is all out of rotors and can not get any more.
we are going to try to save the old rotors.....

thanks for the replies

Next Question,,
what do we have here with the motor mount area ??
I will try to post a couple pictures.
is this ready to bolt on V8 mounts ??

those are the factory 4 cyl motor plates that are tack welded to the body

ok,, so what is the best way to do V8 motor mounts ??

You need to locate V8 frame mounts which bolt on to the chassis and then locate V8 engine mounts which mount to the engine.

What exhaust do you plan on using ?
That will narrow your motor mount options.

if you are doing a small block:
you can keep the 4 cyl spacers if you use don hardy mounts or powerbyace.com mounts (or front mount hooker/trans dapt mounts). If you want to use stock v8 monza mounts you have to cut the
4 cyl spacers off. The stock v8 monza mounts have a few extra bolt holes that are not on your car so you could drill into the frame rails and weld nuts in place or just reach up into the frame and attach nuts or weld the plates.

do you want exhaust manifolds or headers?

We have Headers .

We were told this car had a V8 in it before we go it. But I am not sure it ever did , ? The headers look like they still have the original paint on um ( not burnt off at all ).. and there is no V8 motor mounts.. Ect, Ect,,

those are the hooker 2129 headers, you need this style mount kit with them, you can get it from transdapt, speedway motors, etc. heres a pic of it., its called the front mount system.
