Very thorough resto, great to see. Hope all goes well with the registration process.

I wonder if you could measure the distance between centres of the caliper bracket for me? ie the distance between the 2 mount holes for the Caliper.

Looking good Peter. That rear end looks like mine on the white GT last month. Have fun putting the diff in at that height. With the swinging arm down the axle shaft is at an angle and won't allow the inner shaft flanges to clear. Will need to
jack the arms up flat. Surely someone in South Aus. has those rack brackets spare. Same part from '63 to '72.
If you lower the hoist down so the arms rest on a couple of stands may do the trick.
Glenn. Have you got that caliper mount bracket shown in that pic. of Peters. ?? Isuzu deleted it '70/'71. maybe earlier. They produced a new type of stub axle that incorporates the caliper mounts and are left and right handed.

Dave.

I have never looked that close to be honest but I assume its the combined type.

I've got a '72 parts book and was looking at the calipers and the way they were mounted. It doesn't show the rectangular bracket in the pic. Then I noticed a change in the part number for the stub axle and the diagram looked like a Gemini stub or any of the late model Toyotas and Mitsubishi's. No change to the bearings, seal and disc rotor.

Dave.

An update on the PR90. Rear suspension is almost complete, new rear leaf has been manufactured and installed, re-zincing of brake lines and new hoses also have been installed. The company who made the front and rear brake hoses actually had the details of the brake components for a PR90 on file along with pictures and a service list for each item so we were able to go through the wheel cylinders, front callipers and master cylinder to check availability of parts, they have everything needed to do rebuilds so I will be dropping those items off shortly. I know Dave had all these items refurbished years ago but sitting around it is feared they have just rusted up so we will not know until we dismantle and better to be safe than sorry.
I have ordered new coil springs from Lovells for both the front and rear. They will be married up to Koni shockers. The specs for the leaf and the rest of the suspension components were given to me by a very knowledgeable member of this forum and I thank him for all the help he has given me with this.
I have installed the refurbished bushes into the upper and lower control arms. The top ones are easy to push out and get back in but I had to make a spacer tool for the bottom arms to fit them back in. They are very similar in removal and installation process to the holden torana arms which I have had some experience with but it is not something I would recommend for the novice to have a go at as you could quite easily bend the lower arms. The front suspension is now mostly in the car except for hubs, shocks and coil springs.
Once this is complete We will be sending out the differential and gearbox for new bearings and seals and some items for re-chroming. I have had windscreen seals made that fit the original stainless strip but unfortunately they were made too long and will go back to the manufactured to have 45 - 50 mm taken out of the length and then re-joined.
Once I have completed all of the above then it will be off to the trimmers, so we are progressing.

Cheers
Peter

Great job. Will be a shame to get it all dirty.

What are the specs for the front and rear coils? ie spring rates. My Sport has 'stage 3' coils in it from Japan and i'm thinking to change them to something softer.

Re: the diff. I had my Sport diff "re-coed" a couple of years back with new bearings, shimmed etc. The guy told me that the original sized main bearings are near impossible to get now. He got two sets at the time, one for my diff and I think another member got the other set. He said he had to search all over Aust. to get those sets.

There is another bearing available, but it's narrower and probably can be fitted, if spacers are made to suit.

Hi Peter
That is a great resto
I imagine it had the original carpets in it if not and if you want to replicate I still have the original pieces to model from
They have shrunk with age but a good starting point
From memory that car had black seats and red carpets
If you chose red a very similar carpet is from a VH SLE Commodore made by a carpet company in Melbourne Knox Auto Carpets
They came with good quality cut pile
Keep up the good work and we are all hoping to see it And you next year in Hahndorf
Regards
Flying

Thanks for your kind words guys.
Glen I have sent you a PM with regards to your question.
Thanks for the carpet offer flying, yes the car did originally have red or burgundy carpet but that is long gone I only have a couple of remnants left. I do not think that colour would go well with the current car colour so we will probably go black. My trimmer is a wiz with making everything from scratch so we should be OK.
Car will not get dirty as I do not think it will ever see a wet road again.
Josh I believe you may be coming out here with Craig and Chris in the not too distant future, look forward to catching up.

cheers
peter
