Floorpan: w123 sedan vs. Coupe -- adaptable? - PeachParts Mercedes-Benz Forum

Zacharias · #1 05-31-2012, 12:26 AM

I need to replace the passenger side floor pan of my '78 CD, complete. Coupe floor pans are not made of obtanium, sedan pans are.

Anyone know if the sedan pan can be easily adapted to the Coupe?

Focus here is utility. Not originality.

Thankee

It is shorter so you'd need to cut open some baked bean cans to make up the rest...

W123 sedan (saloon) and W123 coupe differences - information req'd

Since the desired pan is shorter you should not need the bean cans.

I don't know but from my experience I would suspect the pan can be cut and shortened.

OTOH I have a coupe which I am removing the drivetrain from. It is originally a texas car and I believe the floor pan is rust free.

Sorry wrong way round...

What a kipper!

The thing that you will come up against is the position of the bit that attaches to the door frame. The coupe door is longer so you'd probably have to shorten the back end of the sedan floor pan and then lengthen the bit of the pan to make it fit along the door bit (so perhaps baked bean tins would be useful for that bit?)...

... it would probably look a right mess...

'Cos I'm still feeling a bit guilty about not reading your thread properly I've had a quick look for you here

Klokkerholm

I hope the link works - klokkerholm make the panel you want. It probably won't fit well (I ordered one for my saloon and it didn't fit - wasn't even close) but if you're only looking for an approximation then perhaps it will do. I paid (and got refunded) about 120 euros for the klokkerholm panel I bought (and then returned).

I was going by what's available on this continent:

1976-1985 W123

I have my doubts that body sheet metal can be shipped for a reasonable cost from Europe to Canada....

Sounds interesting as I actually need most of the left side too, but was figuring on just having a section welded in -- but the right isn't worth messing about with.

HOWEVER, these days the shipping is the killer when you send stuff either way across the 49th via UPS or FedEx Ground.

Anyone have an idea what a floor pan would weigh?

We'd have to check out what UPS would want to light up that barbeque.... or if perhaps the post office would move it.

Density of mild steel is about 7850 kg / m^3

My floor pan is about 0.8mm thick

There's approximately 1.5m X 1m for each side of the car on the replacement panels for the saloons.

By my calculations that comes in at 9.4 kg

I have a fellow interested in my Limited slip diff from canada. I think he is going to pick it up in Maine from a buddy's house. the weight of a floor pan is not that great but the size will make it expensive.

I inquired last year about an '85 diff and it would cost a fortune to ship one of those here.

The pan might be doable if you could cut it into front/rear sections and stack them into a box.

Let me have another look at the car and determine exactly how much pan I can get away with. This car is on life support so I'm not hooked on originality here....

I've changed my calculations in post #8 - I got the dimensions wrong.

Ah, thanks, 9.4 kg or thereabouts can be done through postal shipping, though not sure about maximum permissible dimensions. Will have to look that one up.

Incidentally, I have been in touch with fixmyrust dot com as I saw a note that they are actually supplying Klokkerholm parts. They told me that the catalog Klokkerholm supplies to them as export customers seems to cut corners and the Coupe is one of them. They are inquiring now about a special order.

Stretch · #14 06-01-2012, 01:04 PM

Well good luck with the special order.

You can get them here - I can send some links to you if you need a price comparison to make sure you don't get a "special price for you my friend"!

If I remember correctly from my chats with a forum member about shipping a sedan floor pan from the US to here (yeah mad right?) the dimensions exceeded the USPS limits. They've got this girth and length combination weird thing going on...

Sure. I don't imagine a special order will be cost-effective, unless they can somehow piggyback on a regular shipment that happens to be scheduled.

I don't doubt it, I just had an Italian freak out on me (eBay) at the cost of shipping a 1/18 scale model across the pond, even on surface mail, so I cannot imagine what floor pan bits would ring up at.

But in the case of possibly bringing stuff from the US to here I think the rules are a bit broader. I know I have seen packages of startling size at my local post office, destined for the US.
