    Highly unlikely i know, but if anyone has an already modified cross member to suit an S13/14 gearbox swap, that they're willing to sell, let me know please :)

    It's quite easy to modify a standard one, but you do need to weld.

    Nice find JB - £190 including duties or cost of welding tools (or hiring) + hassle factor. I personally love the bushing idea on them too.

    Watching with interest Mr. T. Hope it transforms your motor.

    Not pretty but it worked just fine - took about an hour with an old arc welder (that's all I had at the time).

    I suggest - when looking at Kameari Engine Works parts - that going direct to Kameari's online catalogue is better than that of any of their so-called agents or re-sellers.

    Here's a link to the page with the crossmember:

    http://www.kameariengineworks.co.jp/Catalogue-v3/catalogue-071.pdf

    Note it says (to avoid potential confusion) that it's for the 71C type transmissions. It also mentions that it's suitable only for S30/S31 bodies dating after September 1972 production, with the later type mount brackets in the bodyshell.

    I have one.
    It needs a rework on one side as it was made before I acquired the "jig piece"
    I can do this prior to selling it.

    That does look good, and not having the necessary hardware or experience to weld one myself, I may well have been tempted.
    Think i would probably of tried to get it done locally tho before relieving myself of close to £200 notes :rolleyes:

    The price in Japan is perfectly reasonable, and Kameari are a proper business.

    Has anyone come up with a definitive distance that the bolt hole should be offset? I think the last time this was asked, no-one in the know came up with a figure.

    I have seen a cross member that is already offset. Anyone know what this is from?

    This seems pretty thorough: 1 3/8" apparently.

    Err... not quite fantastic:unsure: but it now lines up properly with the mounting holes.

    Looking at Pete's latest unmodified crossmember it's different to mine so am I right in say that the crossmembers for the 4 and 5 speed gearboxes are different? If so that might be why there is confusion John?

    There is certainly a difference in the mounting method from early to late cars

    Early cars had a vertical bolt on each side holding a cross-member up where as on later cars there were horizontal pins through bushes (one per side) holding the cross-member in between shackles

    It's not that Steve it looks like Pete's crossmember has a curve (fore and aft) mine was straight across. It might be an optical illusion.

    I believe the mounting positions for both 4 and 5 speed are the same as I've just swapped from a 4 to a 5 and used the same gearbox mount and cross member. As Steve said, the early cars had the vertical mount and all others had the horizontally bolt mounting. The 280zx hard a curved cross member which may then require less of an offset adjustment for the hole. It will still need cutting though so it doesn't really matter which you cut up. I've come to the conclusion that around 35mm is the approximate amount of adjustment required. The reason it is not critical is due to the clearances for the various bolt holes and the rubber mountings of both engine and gearbox. This is why some people can get away with 25mm offset and others nearly 50mm. you can make either fit. As your modifying the cross member and shortening the prop, you could also take the opportunity to relocate your engine further back (as was done successfully with big sam) and improve the handling.
