Convert a 2+2 to a 2 seater - discuss.

(1/9) > >>

PeterAllen:
I've had a bit of a web search but I can't find any discussion on this. I guess the USA is probably the only place where someone might try it but they have plenty of 2 seaters anyway and seem more interested in making them RHD.

Is it merely a 'cut - trim - shut' requirement? I think the doors are longer and might also have to be trimmed or 240z doors fitted. Just curious.

zzzzed:
doors  are longer on a 2 plus 2 roof line is different and the rear quater windows are also different. besides it being un safe, for what it would cost in man hours, it would be cheaper to buy bennys 2 seater and just drive it
 

Sirpent:
Everything back of the firewall is a different dimension.

On the floor pan just before the upward bend to the firewall there is a seam that runs across from one inner sill to the other, these spot welds are released to allow the 2 seater rear to be welded in place.

The sills need to be sectioned at least 70mm back from the floor seam on the inner side, and another 70mm on the outer side to meet repair industry standards, if there is an inner reo the the reo needs to be sectioned 70mm back fro the inner cut and the outer 70mm from the center cut to create a stagered or step section, butt welding the sill sections together is structurally unsound and is not passable.

This 70mm staggering is the minimal measurements between sections, the longer the staggard cuts the better.

The window pillars have to be done the same way as discribed with the sills.

And if the rails cannot be released for a cut section with the rear cut, then the same stagering procedure needs to be done.

Hope this helps.

PeterAllen:
Thanks John. If I have read you correctly you are referring to grafting a 2 seater rear onto a 2+2 front. Though some of the steps would be similar I was trying to ascertain how a 2+2 itself might be modified to a 2 seater wheelbase, shell shape, etc. Purely hypothetical.

If someone has a photo of a 2+2 shell in the area behind the front seats I would be interested to have a look. Thanks.

Sirpent:
Peter as Mick stated it wouldn't be worth the hassle, you could use 2 seater doors, but it would mean taking the better part of 15cm's out of the roof and sectioning it.

The rest of the sectioning on the sills and floor would have to be done to the degree I mentioned previously.

The reason I know about cutting and shutting a Zed is because I did it on my panel shop partners 260z 20 years ago after he wiped off the front and we found a doaner front end.
