RHD AMX

It appears the red oxide on the pumpkin held up well for 50 years, is it Twin-Grip ? An old nail in the leaf spring was thinking out side of the box and most likely stopped the rattle. There are date codes stamped on the Main Leaf near one end. Is there a place in Australia that can re-arch and re-temper your Leaf Springs ?  Thanks for your work taking and posting pictures and progress, I for one enjoy checking it out.

Yes, I have a spare 343 and like yours it has no weight on the flexplate. The one on this vehicle could have been from another model or a bad balance job. The white paint mark and letters CN make me think bad balance job.
390 AMC engines are rare in Australia. Aussie 70 Javelin only far as I know, and only 70 of those assembled here.
The red oxide on the diff did hold up well. Coated with black paint that came off easily with the pressure spray, was a surprise to see how good it was. Hidden away with black paint again now for someone else to find in another 50 years. It is a twin grip.
Plenty of spring places here, but in about 1983 I added a leaf and cold reset a very similar springpack on a 1979 Toyota Hi-Lux utility. Don't mind doing it again if need be.
Thanks for your input. I would be struggling but for this forum and being lucky to have a very original Aussie AMX as a template.

Finished painting suspension parts yesterday. Running out of places to put things.



Looked inside the starter. Very dirty but brushes looked good. Cut the mica segments down. Would turn over but not pull in. Try again.
After the third time apart and sanding every earth finally had a win.
Clean the outside and paint next.



Got a surprise when I investigated the air cleaner. Factory correct for 4 barrel 343 off Aussie AMX#24 on the left.
Ring in on the right came with parts for AMX#14, suspect it's from a two barrel engine. Looks like a big air flow restriction. Cut it out.

Thanks Ross, I'm learning plenty.

Today I found out more.
Reading a post from 2017 in V8 engine section I realised the carburetor ( M7A 4624S ) is for a 68 343 manual car.
Interesting it was first 4623S ( correct for 68 343 auto ) but the three has been overstamped with a 4.



Did some research in the parts book and I would need about seven parts to go back to what it was and about 11 parts to make it the same as a 4663S which is the correct carby for our 69 AMX 343 auto.

If I could find a correct 4663S I got international shipping and most likely a carby overhaul kit ahead of me.

Looking today I can get a new edelbrock 1905 AVS2 650 in Australia.
I realise to keep my air cleaner housing I would have to alter the inside to suit the bigger carby mouth.
Can anyone please give me advice if other than that its a direct fit, edelbrock AVS2 to the factory 343 manifold.
I reckon if I need a spacer, adapter plate the extra height might kill making the factory air cleaner fit.

That date code stamping is interesting- I've never seen an M like that and I have several M7 carbs. Did they final assemble Carter carbs outside the US? It looks like they started with the basic casting and then finished them somewhere else and stamped the month portion date code and altered the PN if necessary.

Steve_P wrote: Misc- absolutely no need to take the timing cover dowels out as you now realize. The leaf springs had a PN ID and a date code on the shortest spring. Most people burn out the rubber bushing material with a torch; it's quick, but it makes a mess. The early Mustangs use the same leaf spring clamps but their kit includes an extra one.

Steve-P, Thanks for all the information.
Regards Carter Carburetor alteration outside USA, I don't know.
The carburetor in question was altered from auto to suit a manual.
Far as I know Australian Motor Industries that did final assembly of the KCD bodies over here only sold automatic Javelins and AMX's.
I do not know if their rebel or ambassadors included manual transmissions.

By the way I replaced that steering part like you recomended in a previous post. One of your fellow countrymen generously helped out.
Super glad I joined the forum.
