Flanders 41 Report post Posted December 30, 2022 I've got a TKX 5-speed going in, but have a few questions about the crossmember mount that came with the kit. It's their "x-factor" mount. It's quite a different shape than the factory mount, and instructions (should I choose to read them) are pretty vague. I'm curious if the attachment points on the frame are on the front-side, or back-side of the original crossmember mounting position. Original mount, for reference: Was hoping someone can shed a bit of light, otherwise I'll just arse around with it and see what fits best once I have the engine+trans hanging in the right position.

jmlay 66 Report post Posted December 31, 2022 While I have no experience with a top loader or the tkx, I feel comfortable stating it goes behind the cross brace. The tkx is a longer transmission than the toploader, based upon the measurements I have seen online. The answer will be clear when you have the transmissions next to each other.

NeverNervousPurvis 1 Report post Posted December 31, 2022 I have a TKX in my 69 coupe and it is mounted with the second bracket that you have pictured, the oblong holes are towards the rear of the car, so based on the picture I would say it mounts on the back 1 Flanders reacted to this Quote Share this post Link to post Share on other sites
maxum96 29 Report post Posted January 21 I have a TKX in my 70. But I have a different transmission mount from those. I have no idea what brand it is as it came with the car. The first mount you showed should work just fine. Quote Share this post Link to post Share on other sites
Flanders 41 Report post Posted January 23 that above pic looks custom :D I've just attached the mount, and have a few notes for anyone else doing this. I used this: I had to clearance the corner of the mount a bit, above the elongated hole (left, in the pic). Otherwise the bracket was hitting the old cross-member mounting point, preventing the bolt hole from lining up. It does indeed go on the 'rear' side of the original crossmember mount. Also found that this bracket is not compatible with the JBA H-pipe (for 351W, manual trans). The right-hand side, lower corner of the mount (in above pic) hits the exhaust. ...so now I need exhaust work done again. Or, I find another transmission mount that fits (the stock one won't work).
