Gsy1-27-190

[thepope540]

If you're sure thats the number I can get a diff through mazda motorsports for $361...

[KrayzieFox]

That's the only one I know of. Not sure if it's the latest revision or not. Call up MM or Onlinemazdaparts and double check.

*************'s welds are better, I bought the one from PG, and the welds looked a little sloppy. The ones I see Sam sell look good. so Crossover FTMFW!

[thepope540]

Thanks for the info. I'm leaning toward just getting a replacement through Mazdaspeed and having it welded. It is by far the cheapest route that I can come up with. If that doesn't pan out it looks like crossover is the way to go.

Oh, fox that is the correct part number. Thanks for the ultra quick response on that!

[Outlawstar98]

Man, just see if PG or crossover has them in stock, any OEM part from mazda takes WAY to long to get to you, Well for me atleast. It sucks!

[thepope540]

When I order through Mazdaspeed Motorsports I typically get things within a day or two. I'm basically ordering through the Mazda dealer network (with warehouses all over the country) at dealer cost. Its a perk for autocrossing occasionally and is available to every Mazda owner. All you have to do is submit race results twice a year. The reason that it can take a long time to get things through a dealer is that often the dealer will sit on your order several days before even placing it with Mazda. This saves them money on freight and also saves the parts department time as they only place orders once or twice a week rather than every day.

Good stuff, glad to be of service :)

And I've heard from others that MM has much better service than regular Mazda dealers, so that shouldn't be a problem. Just get it welded right away. I bought one from PGarage and I think the welds look fine, but I dunno a whole lot about welding either.. so they could be sloppy and I just may not know it.

However, I'd go for the Mfactory one. It only takes a 3-5 days to get it.

If and when mine breaks, I'll be getting the Mfactory one.
