Ok here goes I bought a sr20 crossmember off eBay you may have seen it on there a couple of weeks ago, I got it tonight and it didn't come close to fitting on the s13 mounts, so I removed the s13 mounts and it seems that it needs a much smaller mount, Now I'm guessing they used cortina mounts or something similar . Does anyone know the year model of the cortina that these mounts are out of or a part number? Cheers Luke
