The frame you have looks fantastic. However, the '64-'65 Giulia Spiders require a twin-tube frame as seen below in a photo I "borrowed" from GTD in which you can see the two parallel, horizontally-running tubes that attach to the rear panel area of the Spiders.
From what I have read on the BB, the single-tube frames require significant "engineering" to work in these cars, which is too bad.
Someone will really be glad to get yours, for sure!
Not a car model change, but the top frame was changed on the last of the 101's. Alfa tried to make it less a finger pincher than the one tube 101 frame. So somewhere in production of the 101 1600 cars, a soft top frame variation including red lifting handles, and black handle locking arms was installed on 64 and 65 101 spiders. Rich's offered frame is a very nicely restored example of the earlier, and more common 101 LWB top frame.
Just a short input for the knowledgeable while at the soft top frame subject, would the late (´64-´65) 101 1600 top frame be equipped with a grab handle as in the attached pic?
And the early 1600 and 1300 not?
WoW! lets see. My 65, owned from new has a middle header grab handle like the one pictured. But I believe my 60 LWB spider had one as well. It was a 101 1300 Veloce. The 1300 had the finger-pincher frame without locking handles or red rear lifting handles like Richs sale frame.
Next, as the chassis are the SAME 101 LWB 1300 and 1600, I suppose either frame could be fitted to either chassis. However, captive nuts and holes for mounting to the chassis may differ between the early and later frame, and it may involve some fitting to use either frame in a chassis other than the one built for the earlier or later frame. I have never tried switching frames around.
There was a 1300 101 top frame that had a so called "high-front-top-bow" for headroom, and, I believe later a 1300 101 top frame with a lower front top bow that was not the same frame as that on the late 1600 cars. Perhaps someone can confirm?
The metal had been restored and repainted with holes filled. It is trivial to add a grab handle. As we all know, Alfa used parts until they ran out before going to the next version. Maybe the thing to do is look at your internal mounts and see if this will bolt up or not. If not, don't buy it. If you need photos of the ends, I can take them. Let me know. thanks, Rich
