(DRIVETRAIN) 84-85 Automatic to Manual transmission conversion question
what have you guys done for converting a auto to a manual the holes for the braket are about 5 inches back

There have been serval threads on this swap. The easy answer is to make a new braket that connects to the two. The braket is basicaly a piece of flat plate stock with bracing on each side. The thicker the plate the better.
One thing I've been thinking about is to replace the auto trans tunnel with a manual. I havn't looked to see if spot welds coulds be drilled out to get the tunnels out. I have a parts car with a manual trans I've been getting my parts from for the swap. I need to pull the carpet out to see how easy this would be.

Maybe I didn't make myself clear. For 1984/85 models, use the manual trans support and flat stock to bridge the difference.
I'm doing this swap also. If you need any help let me know. I'm not that far from you.

No, not engine but transmission crossmember. Also the trans mount is different between the A/T and M/T in 84-85. But I don't see how it could account for that much difference in mounting though. That's a long distance between the 2.

That's weird. On Aussie cars Mazda provided mounting points on the body for both the auto and the manual. I recently did the swap and it bolted straight in.

The 2nd gen bodies are the same way, one set of mounts for auto, another set for manual, 2 different bodies. The mounts can be drilled out at the spot welds and installed on another body. I've never compared the shifter hole opening or mount holes between them, that may be another concideration.
