Hello,

I need to buy some rear inner arches and in the description the parts fit
"Inner arch for shallow arch cars 1968-77 "

Is my 1969 1750 GTV a shallow arch model?
What would a GT junior model be considered ? Shallow arch model ?

Thank you for any help. Sorry for this question that is probably very obvious to most here.

Hi there Maire,

Shallow arch cars are "low rear wheel arch" cars AFAIK... Your 1750 which is a 1969 1750 GTV should not be a "shallow i.e. Low Rear wheel arch car"....

The change in rear wheel arch design, hapened during 1967 (rather later in year than earlier) .

I'm happy to be corrected, if I'm wrong.

Hope this helps,

Thomas

Yes a 69 GTV is a shallow arch. With the GTj you would go by the year but best you understand first the difference.

Maire, So now you are confused as you have 2 differing answers based on the perceived definition of shallow. Who is the vendor you quoted "inner arch for shallow arch cars 68-77". Chances are he knows his years and arches. But do you have a 69 GTV or are you wondering if a shallow arch will fit a GTj??

Now I'm confused

Hi Ken,

I appears you have far more knowledge on this topic, than me. Can you explain us (me included) in simple words the differnce between shallow arch and "non-Shallow arch?"... I'm happy to learn more about this... I allways thought we have only have low arch and "high arch" cars... but Maire (the thread starter) speaks about shallow inner archs.... and I was refeering to the outer fender arch design...

Thanks for your help.

High (late) and low (early) are a clearer way to describe the 2 types of arches. The vender uses shallow for late, not sure why but the early would be deep I guess. Different points of reference.

Hi Ken,

Thanks for this... It's much more clear now... But you're right its a bit of a strange designation/denomination... I would rather stay with the High-Wheel arches termini (Later cars as from late '67) and low wheel arch cars...

Anyway thanks a lot for the clarification.

taller, higher = more room for wheel travel or increase width of tire right? how else would you describe it?
I'm just saying there are several different ways apparently used to describe the 2 types of arches used on the Bertone GT and if a newbee finds that confusing, small wonder. nothing wrong with your take on it.

No actual 1750 shell is a low arch

Better to stay in the positive and to say: Of the Bertone GTs, all 1750 (and 2ltr, late 1300 GTj, all 1600 GTj) chassis are high arch; or shallow arch; or taller arch; or late arch.

I agree with most of it with the exception of shallow.

here is the dictionary definition of shallow meaning: 1. having only a short distance from the top to the bottom

no not 69 S1 1750 mine or any S2 1750 that ive ran across in the last 40 yrs

Alfaholics is using the term shallow arch for the late chassis 68-77. See https://www.alfaholics.com/parts/105-series/panels/coupe/inner-rear-wheel-arch/

and have a look at their rear fender offerings discriptions.

I assume they are measuring from the fender line or beltline down to the wheel arch. So Shallow would be a short distance (as in late chassis) and deep would be a greater distance as in the early chassis.

Classic Alfa uses one of the other terms mentioned in this thread. High and low.

hello ken

saw the link... thanks. its stupid isnt it? :)

i think they meant "shallow" meaning the depth of the draw in the inner wheel arches which has less volume than the earlier cars which are deeper. to avoid confusion, its should be called wheel housing (industry term), wheel wells or tubs as the hot rodder's call em here in america.

the later higher arch cars require a smaller wheel well hence their term "shallow". this contradicts and adds confusion to larger later arches. to combine "shallow" to the higher, taller arc of the wheel arches lays the problem for the mix up imho. after all we do in turn ID these wheel arches and cars by looking at the external body work or do stick our heads into the wheel wells?

classica afla clarifies it. simple and concise... the way it should be.

cheers

PS, is it my imagination or are the alfaholics prices astronomical these days? its been a long while since i purchase anything from them

Wow, the "Rube Goldberg" definition or arch repair panels.

Glad I managed to buy the right outer arches many years ago. Pretty sure I would have ordered the wrong ones with this definition

:D, lol.

Maybe this is the only way to be clear: Of the Bertone GTs, all 1750 (and 2ltr, late 1300 GTj, all 1600 GTj) chassis show the most of the top of the rear wheel ... with the car at the same ride height, parked in the Greenwich council car park space number 23, at 2pm on a dry Wednesday that is between a 18 to 20 degree Celius, with a full tank of fuel, original spare wheel inflated to 32 psi, tool kit, jack and bumper. ;)
