Fairlady Z-L Foot Rest Measurements

[d3c0y]

(Topic was split from another thread.)

 

I am installing a factory option foot rest in my 240ZG replica and Alan T is providing some measurements of where to drill the holes. We are also discussing the unique spreader plates under the floor.

Crikey. It's like being given extra school homework...

 

+2 and the measurements for the holes i need to drill for my foot rest!

 

Measurements are difficult (where to measure to/from...) and these things have a habit of turning into something much bigger and more controversial than you ever imagined once a few idiots misinterpret, modify and misunderstand the original data. So here's a pre-resto photo to see what you think of it:

Thank you kind sir, much appreciated. I can understand the controversy, as i'm sure you remember I was one of the idiots that misinterpreted the fender mirror diagram. I atoned for my sins when i repainted my car and moved the holes over (I think it was the pressure of drilling holes in the top of my guards that made me have the oversight haha.)

 

This time i'll mark the diagram with centre to centre measurements to avoid any confusion. I'll try and measure the distances using the chassis rail width as scale but if you wouldn't mind measuring the distance from the drain hole to footrest hole centres that would be great to double check I have it right.

 

Obviously if you are measuring from inside the car and can give any suitable horizontal reference that is convenient that would be great too.

 

Thanks in advance.

Done.

OK, bear with me. I'll see what I can do ASAP.

 

One thing I would say is that the reinforcing mounts are particular shapes, and the outboard one is shaped to fit the curve of the floor. It's probably worth trying to replicate that if making your own mounts, so I'll try to capture some decent photos of them accordingly.

I saw this on Kats thread.

I had a 260z 2+2 with the foot rest and never noticed these on the floor, not sure why? But it was close to 16 years ago I had it. So that might be part of the reason?

I got out and got under.

 

 

The threaded studs on the footrest are 280mm apart, and of course the holes in the mounts correspond with that dimension. The inner mount (as can be seen from Kats' photo) curves around the shape of the floor pan and is slightly flattened on the return edge where it gets near to the floor support U-channel. There's some shape to the outer mount too. They are both spot-welded to the floor panel. 

 

I now have custom seat mount crossmembers on that car (to enable lower seat slider positioning) and the original seat mount crossmembers are gone, so nothing much inside to measure to, sorry. I could try taking measurements from my 1970 Fairlady Z-L's body though, as that car also has a passenger footrest.

Thanks Alan, I appreciate it. What you have given me is plenty of info to work it out.

 

My Aus spec 240Z has cut outs in the sound insulation on the inside, approximately where the bar mounts but one side was damaged due to rust. 

 

The spreader plates under the floor are interesting and I haven't seen these in the flesh before. Gav I'm with you, as the first 260Z 2+2 (series 1 car) I pulled a foot rest from didn't have them either and just had large flat washers.

Maybe this is a HS30 chassis only thing? I see that Kat's 240ZG is a 06/72, so safe to assume it's not an 'early' chassis feature.

What year is the car you took the photo of?

My JDM 77 2+2 parts car was the same, only had the huge flat washers. Perhaps that's the difference between factory figment and after market?

I'm assuming this is a factory cost saving option and if you think about it, it was probably an easier option if a dealer wanted to fit in Aus.
Sine we didnt get different specs like Japan it would be easier than ordering them from the factory like that.

As I said above, my 1970 Fairlady Z-L has exactly the same spreaders/mount plates spotwelded to the floor and the design was exactly the same, and certainly carried from 1969 through to late 1973. My GP Maroon 1972 Fairlady 240ZG is just a few chassis numbers away from Kats' 240ZG and of course the design is the same. The footrest was standard equipment on all 'Deluxe' models in Japan, but an extra-cost showroom option on the 'Standard' models. I believe the factory put the mount plates on the floors of all the Japanese market cars (certainly between '69 and '73) to allow the showroom optioning and because retro-fitting would require welding.

 

Car in my above photos is my (GP White) 1972 Fairlady 240ZG, the ex Masami Kuwashima car, now part way through restoration.

Sorry I've misused the the HS30 code by lumping the plain S30 models in with them. What I really meant was that maybe it's a pre-MY74 thing, and/or that no export markets received the spreader plates. I wonder if there are any HLS-30 cars in that have these? I would think that's not the case, as this is the first I have seen of them.

If an AU market 260z owner with the foot rest could post pics, that would be helpful!
