RyGuy is looking for a slave cylinder for his 70 Goose....
RG, your options are one of the following
1) Rebuild your original aluminum version, which is unique to the GOose and a couple of Fiats (2300 & 1500 Osca Fiat #4039673) and perhaps a Maserati or two. Kits for an early Fiat X1/9 will perhaps fit your piston....depending on which version of piston (at least three versions) you have. All are a 3/4" bore Girling part.
If your bore is bad, you can have it sleeved with brass/bronze for a reasonable amount of $$.
Kits are listed under Beck-Arnley #071-5789 Wagner F103530 But these are drying up if not gone off most autopart shelves....and again, your piston may not fit the kit....depending on what you have.....
You can also buy the cast iron X1/9 version (see #3 below) and gut it for the all the parts. Beck-Arnley and Centric list them on eBay for $20-30, use the innards to keep the proper aluminum version on your car original!
2) You can try and find a cast iron version of the original, still available from Fiat's Plus in Santa Cruz CA. Chris should have what you need. He may have them under the Fiat #4039673 for the 2300 and 1500 Osca.....
3) You can fit a late model X1/9 cast iron version to your car, but you must space it out about 4mm and use slightly longer bolts. The mounting bosses are not centered (that would have made it SOOO easy if they had done that....) This cylinder is an exact mirror image of the original, so you need to be aware of this bit!!!
All depends on what you want to do!
The attached picture is of an X1/9 "wrong one" cylinder on a bellhousing! Note the slight space between the cylinder bosses and the bellhousing. If you cranked it tight, you may risk pinching the bore and locking the piston, or pulling the threads out of the expensive aluminum bellhousing! Ouch!
