A perfect (or not) example of the kind of crap parts we are being sold. That mount hole in the tranny is round, last time I checked.

A perfect example that some providers do not care much about what they sell, or their clients.
It's called the 'bottom line'...............

So what do you do? Stop buying from them until they straighten up, and let them know LOUD & CLEAR!

I sent the link to this thread out to Centerline, Vick Autosports and Mr FIAT as a heads-up on this issue. If anyone feels like others ought to receive it, feel free to send it. I think most of our other vendors here in the USA, like Di Fatta, Alfa Parts out in CA, and other specialty shops offer mostly OEM parts. We won't have these problems with original Alfa ricambi parts.

Thanks for the interest and support.

Di Fatta Bros sell aftermarket parts. I trust them more than some others because they sell the same parts that they install in customer's cars.

I didn't know that about DiFatta, but anything I've bought from them was a perfect part. I like dealing with them because they absolutely KNOW Alfas.

Here is what can happen. You won't buy from a vendor because the parts they sold you didn't fit, didn't work or didn't last. You then choose to say nothing and boycott the vendor. They have no clue why no one is buying parts. They are not making any income, so they close their doors. One less vendor, less competition.

One could have called, written the vendor to notify them as to what the problem is and try to work it out. The vendor then can go to the source and see where the problem is. The vendor should check for QC and send the bad parts back asking to have the issue fixed.

OEM parts will dry up and thn all we have is after-market. Only when someone says something or the vendor does QC, will we have parts like OEM.

Agree, and I do so, always complain when a spare is not right made and let them know, I just trying to alert others about this bad fit so they first do check the sparepart before intalling it

Guys, we as consumers should not have to be the QA inspectors for suppliers. It is up to the manufacturer to produce the part to spec, assuming they care about their product quality. And further, it is the responsibility of a good vendor to ensure that parts they are sourcing and offering to us fit the car. After all, they are Alfa owners, too!

This is the very reason I sent out those links. We pay for the part, we have a right to expect an acceptable level of quality.

With the rising prices of 102/106 cars, manufacturers have rushed into the market with previously NLA parts that are, at best, vaguely shaped like the original.

I admire Classic Alfa for their good service, but for awhile I was sending them a weekly “does not fit” report. I’ve got quite a pile scheduled to go back to them. They’ll pay the freight, but it’s a hassle none of us need.

Many of the parts are polished trim items, which have to be, themselves, trimmed to fit. Much work, after which we discovered that they simply cannot be fitted.

About 10% of the silent blocks had unusable IDs or ODs.

The sad fact is that true OE is NLA, so we have the choice of paricipating in the QC process, or going without.
