Panel Gapping a HQ Coupe ~ any tips or advise?

Good Afternoon Gents,

I hope you've all had safe and happy Christmas, and new year to follow!

Dad and i are up to assembling the HQ monaro which we bought several years ago as a freshly painted shell... so effectivly we have embarked on a nut and bolt resto backwards! we now have the roller cammed 308 in and running. We have done 95% ourselves and it has been a steep learning curve, being our first full build.

The front fenders have been hung loosly to allow us to assemble the engine bay so basically im set to start at rear and work forwards attempting to gap a car that was far from perfect to begin with.

I am after anyones advise who has experience gapping one of these cars. The main drama i can see is that because we had the chassis off (to sandblast, paint, re-bush etc) i think it might be troublesome to get it back where it started (somthing that would have been a good idea to measure in hindsight). I figured that by loosening all the chassis bolts and using some lage truck ratchet straps to gently pull things around might be the go.

Any other ideas, tricks, or measurements that anyone knows before we have a crack at it?

Thanks Guys, and a happy new year to you all.

Brenton.

Start with the door - rear quarter - sill panel gap, then assemble the front carefully and slowly adjust the panels and chassis to suit, the rear bonnet gap must be even across the vent panel and evenly spaced which will help keep the front square when lining up guards. Take your time.Good luck.

Assumtion is the mother of all stuff ups.

If you are talking about the front of the car not being square, you can loosen off the 2 mounting bolts on the radiator support and move it around to suit.
You can also use shims there to get the height right for the bonnet too.
AS for the other panels, it is a slow task of fitting and adjusting.
One hint I will give you on the bonnet hinges, if the back of the bonnet is too high, common sense will tell you that you need to lower the hinge to drop the bonnet, this is not the case.
You actually have to raise the hinge to get it lower.. freaky hey?
Caution, when you make this adjustment, it will drastically change the position of the bonnet and you will need to adjust the forward/back to suit

In my opinion, what i have found best is to actually assemble the whole front end on the ground first. (radiator support, nose, front guards and inner guards) all in one hit. Plenty of blankets and sheets etc. It is much easier like this to get the front gaps all sorted nicely then you just put the front of the car on jack stands, pull the front wheels off and get a few mates round to help. It pays to tape up the area around the cowl panel first to avoid scratches to any paintwork. three people to lift and one to watch for clearance is optimal.Of course you need to have the doors sorted first and in a perfect world all the panels would have been pre assembled before paint to make sure of a good fit. The bonnet goes on last and above all.... Take your time there is no rush! the project has taken this long so far so if [Naughty Pottyword] aint workin then just back off and have a beer then have another go in the mornin. I actually pull the whole front clip off the car for any major work especially engine removal as it makes things soooo much easier to work on. Just my way of doin things anyway.

Old Holdens never die, they just get hotted up.

i'll add this, on these old sh1tters, its alot to do with bending, tweeking, and loosening, and pushing and pulling, and then scratching ones head, then heaving, and then sometimes even slotting, and then starting again, try a 65-66 mustang, you'l find this piece of cake.
