Differencies?

[stratosphere]

This is a "new" question about Square arch GP 4 cars.

Looking on different pictures I can see that there is a difference between how the square arch are attached to the body.

On some cars there is a small edge about 1 inch from the actual arch on the sides if the body, and on other cars they are completely smooth in this area.
(se pics on cars below)

Can anyone explain those differencies?

Pics below comes from one replica and one original reworked ex stradale car, but I've seen this on other cars as well.

How do I make pics visable directly i posts so one doesn't need to open them seperatly?

Hi Luigi, I think it depended on the particulat car used. Some works cars were originally stradales and the arch extensions were riveted onto the tub for the sake of speed of preparation. Given more time they were smoothly attached. Rear body arches were bonded on.

Guy all works cars were originally Stradales either finsihed or not.
Lancia was selling a kit to modify the Stradale body to a Gr.4 one. Those who didn't have funds to make or buy complete lightweight Gr.4 bodies chopped the Stradale body to fit the kit. On the round arched version the kit replaced the complete exterior part of the body so it looked smoother. For the square arch the kit maintained a portion of the exterior part of the Stradale bodywork and only added the square arch part. It was easier to fit and that's what you see in the 1st picture.

Here's a picture of the FIA homologation for the round arched Gr.4 body:

Add one picture and you can see it, add more and they appear as links.

Sorry, Luigi, I can't see a difference :confused:

Sorry, Luigi, I can't see a difference :confused:

And I thought it was just me, thanks chris :)

Note where the square arch meets ths bodywork, there a "lip" in one picture, not the other.

[Bernard]

Is "that lip" a shadow ???

[stratosphere]

For those that don't understand see the difference

Look carefully where my arrow points.

On this car you can see it, on others (like the red one above) you can't

Are you sure it's not just a reflection?. I'm sure the circumference is greater than the original stradale wheel arch anyway isn't it?.
I could be wrong!.

Having seen Guy's car in the flesh, there is no lip there.

The "outer" diameter of the extended arch is the same as the Stradale arch, the junction to the body is indeed larger. When adding the extended arch, the stradale arch is cut back.

[tryphon]

As I said in my previous post Gr.4 cars could either change the whole bodywork for the lightweight Gr.4 one (no lip) or chop the Stradale bodywork (lip). That is no reflection and is actually quite good work compared to other Gr.4 cars of the time...

[guy mayers]

Whoa there boys!

The black car in the first picture is my car and I assure there is no lip where the arches on either of the extensions on the rear body panel or the tub. The extensions were carefully grafted on. Anything that appears to be a lip is a reflection I assure you! But I'm flattered if anyone took it to be an original!

I assume the red car is an original but to be honest, I can't see any lips on that picture either. Tryphon, I take your point about all Gp4 cars being originally stradales!

Whilst I've seen pictures of Gp4 cars with extensions riveted to the tub I can't recall seeing any with extensions riveted over the rear body but I wait to stand corrected. I also assume that the picture you posted ofthe homologted car shows the Giro d'Italia style front end?

Cheers

The b&w picture is taken from the homologation papers dated 11/74. The front body work only ever appeared on the Tour de France/Giro d'Italia as far as I know.

Yes the picture's origine is in the FIA homologation papers. The front was homologated for Gr.4 use too. The white parts illustrate the "add-ons".
It's only possible to find the "sloppy" jobs on period pictures. Current cars have been straigthened out, given the price, to appeal to modern owners/buyers.
