attached the starter to the adapter plate...

Brought the TII trans and got it positioned under the miata so it can get accustomed to it's new home

I ordered a throwout bearing, but it hasn't arrived yet :evil: , so unfortunately the tranny will have to come back out again, that's why the clutch isn't installed either.

Here the tranny is bolted to the adapter plate:

We supported the rear of the tranny with a ratchet strap off the front roll cage bar so we wouldn't have any obstructions in our way under the car. I also trimmed the shifter opening a bit to accommodate for the TII sitting 1/2" farther back than normal.

here is the stock TII transmission mount:

What I ended up doing was taking it off and rotating it 180 degrees so the "bump" to clear the exhaust is now on the driver's side.

Next up, I took the seats and carpet back out:

and then ground the undercoat off of the trans. tunnel where we would be welding

driver's side

pass. side

We measured for the brackets and ended up using 1/4" steel that was 4" wide. I wanted the brackets to be above the stock TII mount so that i could easily remove the transmission without having to take the TII mount off, and also so that I don't lose any more clearance for my exhaust, because ground clearance is going to be a precious quantity.

I marked the holes on the TII tranny bracket on the new bracket, and drilled them out with a drill press. next, we welded in 2 12mm bellhousing bolts I had leftover and lopped off the tops so they would clear the tranny tunnel:

I left enough room to be able to fit a lockwasher with the nut and still have a few threads sticking out past the nut.

Then we bent another piece of 1/4" metal to the shape of the trans tunnel and tacked the above bracket on

and welded it up:

Here's the bracket how it will sit on the car:

pretty slick it you ask me

Here it is burned in on the car:

Here's the finished product of the driver's side bracket. I did the same thing as the other side as far as keeping the mount above the TII stock mount, and welding the bolts to it:

and a shot of it burned in....

Tranny mounts- DONE

Here's a shot of the welds from the inside...the paint got a little burnt up, oh well

pass side.

driver's side:

and since i was in there, here's a better shot of my NRG Thin carbon quick release

If my mazdaspeed diff mounts come in this week next weekend we'll start on the rear diff, if not, there is plenty of other things to keep my occupied.
