Starting to think about how i'm going to rebuild the two Lazer ZX-R's and am wondering if these knuckles off the Re Release Optima will fit on a Lazer ZX-R, or if they're sized differently for the Optima Re Re's bushings. Any other Optima Re Re parts, such as the hinge pins?

They are the same dimensions but I believe they swapped the lettering L and R. I’d have to double check but I recall that from when the optima rere came out.

You don't happen to know if the Optime Re-Re's gear diffs fit. Do you?

I saw I could get a new bumper for a lot less than I paid on Shapeways for a reproduction.

No, rere diffs diffs larger outdrive bearings. I want to say it’s a 10x15 where original was 8x14. You can’t get a 10x14 bearing so it’s a no go

At first I thought one of my recently acquired Lazer ZX-R's was a mk2 because it didn't have the funky front-upper rod end, but now I'm thinking a previous owner drilled some holes in the uprights as a mod. Is that what it looks like to anyone else?

That looks correct for mk2, so does the front shock tower and chassis with 6 battery slots.

Are these caster blocks in any way similar to those of a ZX-s or ZX-5? I actually got a set of drmosfet's ZX-S reproductions out of curiosity when I ordered a couple of other parts I needed.

ZX-5 suspension is very different and the parts really aren't interchangeable with the older cars. The arms are much narrower Also, there are different models for the arms and c-hubs, and they can't be mixed and matched and usually require changing the universals due to length differences.
At most you could maybe use the rear hubs, but you might need to use different universals because the offset is different compared to Lazer ZX(-R) rear hubs.
