Hello chaps and chapettes. This car has been hovering around the shed for a while now but it's finally getting a little bit of attention.

It's an Opel Monza, obviously, and will be getting VH commodore front and rear and a Group C bodykit. It'll also be getting a new Holden V8 heart : )

The owner supplied me with a good VH front cut with all hanging panels, so that's going to be a big help.


Posted Image


I picked up a rear cut from a VC so I can install VH tail lights, as the monza ones look like crap! Plus the more recognizable the car is as a commodore the more people will realise it's a 2 door. At the moment it looks a bit like a retarded celica : )


Posted Image


So first things first, get it in the shed. Of course all the other times I've started it there were no dramas, but the time it's going inside it wouldn't start. This is when you find out it's a heavy bugger to push : )


Posted Image


It has some rust issues. Both sills, front guards (which I'm not using anyway so it doesn't matter) rear quarters and wheel arches, boot floor, a bit around the hatch, the hatch itself, the front strut towers, A pillars, doors, sunroof, radiator support and chassis. Apart from that it's really solid : )

It has this cool sticker on the windscreen too.

Well now it's time to start tearing it apart.

Well even though it's a fairly basic car as far as getting to the nuts and bolts, it fought me the whole way! I snapped about 15 bolts getting the front apart. The rust has worked it's way into most of the bolts, so they're really tight. I even managed to open up a couple of knuckles when some bolts broke. That's always fun hahaha.


Posted Image


The motor mounts have a little shock absorber on each side. These things are COOL!


Posted Image


Getting the factory oil cooler out took ages, but it's out now!


Posted Image


The drivers side A pillar has seen better days, but it's fixable : )


Posted Image

Posted Image

Posted Image


This is the drivers side chassis rail. It's lovely : )

Posted Image


The drivers side headlight housing has this big seam around it, which I'm pointing to. I can push it backwards and forwards with my finger, and it makes a nice crunchy sound : )


Posted Image


I know it looks like nothing, but I could have thrown a party at this point! The seats were held in with fairly long allen head bolts, that were rusted in, and it took me about 45 minutes a seat just to unbolt them!


Posted Image


Under the carpet in the rear, there are two steel flaps that make the floor when the rear seat is folded down. The pic doesn't show it but the paint on them is amazing! It's completely untouched and they look brand new. That's good, because nothing else on this car does : )


Posted Image

Posted Image


There's a few small bits of rust around the rear hatch. Nothing to major but they'll still need to be cut out and fixed.


Posted Image


This is the rear of the drivers side rear wheel tub. The intersection of where the tub meets the floor is pretty knackered.


Posted Image


Drivers side rear quarter.


Posted Image

Posted Image


The rear of the boot floor doesn't look that bad in the pic, but it all needs to be replaced.


Posted Image


This pic is just because : )


Posted Image


Passengers rear quarter is a bit crusty too, but we already knew about these areas. So far there's been no real surprises.


Posted Image

Posted Image


I know I'm posting a lot of boring rust pics, but these are more for the owner to see than anything else.

Posted Image


It's amazing how much better it looks already just by pulling the bump strip crap off the sides.


Posted Image


Doing a quick test fit of the rear flare, just because I wanted to : )


Posted Image


It's going to need a bit of work to make it fit properly, but it's going to look awesome when it's done.


Posted Image


The front bar/spoiler.


Posted Image


I'm not really sure why there's these clumps of poo on the bolts holding the rear side glass in, but it's there anyway : )


Posted Image

Posted Image


Getting the interior out was a bit of a mission, but there's enough out now to keep me happy. The only thing left that I haven't done yet is remove the sunroof, but that's for another day.


Posted Image


Time to yank the 3 litre monster and getrag 5 speed. The 5 speed will be going back in, but not with this engine :)


Posted Image

Posted Image

Posted Image


Well that's it for now. It's taken just over two days just to get to this point! The owner also has another one of these so I've been trying to be as careful as possible when removing opel parts, even though we're not using them on this car they can be spares for the other car.


Next job will be to strip the paint and get some etch on it. Then the chopping can begin : )

Looks like a mash of VH commodore and UC hatch. Looking foward to watching this build come together.
Any chance of it being painted up like a Brock group c racecar?

I say this as i have seen photos of the protype one HDT did in the 80's and it look fantastic.

Well I did a bit of digging on the old beast yesterday. I attacked some of the bits with a wire wheel, and used 24 grit discs for the rest.

Time to start hacking paint : )

I don't know of aussie commodores have these lovely joins at the front and rear of the roof like this does, but geez for a production car the finish is amazing. Pity they couldn't put the same effort into keeping the rust out : )


Posted Image

Posted Image


Obviously the sills are knackered.


Posted Image

Posted Image


The rear wheel arches have defnitely seen better days, but seeing as the big flares are going on a lot of this can get cut away.


Posted Image


I was able to snap the lower front edge of the rear wheel arch off with my hands. That's always a good sign hahaha.

With the outer panels stripped I covered the lot in rust converter.

Well that pretty much took care of yesterday, and what a fun day it was too : )

You've got some work ahead of you I see. Did they use thinner steel on these things or is still 1mm?
