Hi
I have picked up a works 91 dogfighter and when stripping it down to clean i noticed the front diff housing was broken (metal one), anyway does anyone know the part number so i might find a replacement, or do any other diff housings fit from other yokes, any help would be great.

thanks Mick

ZC-300F and maybe another letter to indicate aluminum but not sure might be a "C",
or maybe "A".

The bulkheads were changed to Aluminum for the works 91 onwards, the YZ-870c had magnesium bulkheads both are interchangeable.

Yes definitely aluminum for 91 and 93, didn't mean to confuse just not sure of the letter indicator for aluminum bulkhead. I have a ZC-300FC but can't tell if it is aluminum or not but it does look a little different than the magnesium, just doesn't look like aluminum.

Generally I would say if it's a shiny it's aluminum if its matte then magnesium.

ZC-300AF for front aluminum and ZC-300AR for the rear, and they are not so easy to find

OK brightboy what does the 300"FC" stand for and you know what I'm talking about?

Both of my aluminum fronts came with the ZC-300FC on the packaging...But they say for works' 93 on them. Dont know if there was different packaging for the 91 bulkheads.

Thanks Joe, kind of thought the "C" was the letter code for the 93 and maybe "A" was for the 91.

Are the rear bulkheads aluminum on the works cars? I have yet to see a factory aluminum rear for sale anywhere

After the 91 works, aluminum was the norm for this type of bulkhead. As you can see, for the 91 "A" stood for aluminum. No need to mention it for the 93. The 93 used FC for the front, the "C" was used for the 93 works cars.

You guys are going to have to stop with the Yokomo parts........................or show some builds to help me cope

Good luck, what was it that Charleton Heston said " you'll have to pry them out of my cold dead hands"

Too add a little confusion. I have just dug out the two spare bulkheads that I have. The one on the left has a different profile where the shock tower mounts to the one on the right. The left one is also 1g lighter according to my super accurate crack dealer scales.

The one on the left came off my works 93 which now has a nylon bulkhead. I can't be sure if it has been hand finished at a later date.
