How interchangeable are 318 harmonic balancers?
As I mentioned in my introduction (link: New member with an interesting story. ), I'm working on a '71 Chrysler VG Valiant with a 318 from Australia, and amongst a couple other things I'm currently working on, I'm in the middle of changing out the timing chain. During my testing on the chain I noticed the TDC mark on the harmonic balancer didn't line up with the marks I got when I used my TDC tool, so as long as I have it out, I'm wondering about replacement options.
The owner of the vehicle wants to keep the car as original as possible, but I can't find a da** thing when I Google the P/N found on the inside of the original damper, so here are my questions:
1. How interchangeable are these? I see all sorts of dampers available for 318LA's, but I don't know which one(s) to pick. Or avoid.
2. Given that this is an Australian engine, would there be a US equivalent damper I could use, or is the same damper used regardless of geography (i.e., here in the States)?
3. And lastly, is there an aftermarket damper I could use that looks like this one? I'm not trying to "pull a fast one" on the owner, but rather the back sides of the dampers I'm seeing online don't match what I have here in my hands.
Any and all useful input will be sincerely appreciated!
Thanks.
Jim
