New T5 info. The "shift lever" the thing at pins to the shift rod and has the detent ball in it and the cup for the shifter stick is now officially mystery metal.
It looks like steel
Got steel like weight
The case is harder than 1018 and makes grey gritty chips
the core is softer than 1018 and makes very nice looking copper colored chips
it tack welds fine with tig and steel filler
it cracks directly down a long bead with both steel and 30 filler
Welding fumes make your tongue feel funny and cant taste right for days
Oh right. And the damn freeze plug is annoying placed. I ought to be able to find some sort of boot that'll work somehow but I feel like I'm going to end up just ******* using some rubber sheet and RTVing it to the housing.
Milled the hole for the tailshaft extension. Next up I need to calculate how long it needs to be extended. I may also need to add some sort of support around the seal. Give the shaft something to ride on. Maybe just a simple delrin bushing will do.
you're going to slide the original t5 block back on there and drill the rod in about the right spot for the roll pin?
Also, FYI, it looks like any of the "shift lever" fits the rod and has the correct detent and nipple thing to work in the tranny, the cup location is what changes. So if you can get a chevy or jeep one its fine.

exactly. And then stick the other shift lever thing out the back. Need to measure and decide how far then send the shift rod to Sean and his moto-horse-lathe for a new one.
I brazed it. It would look way better if I hadnt tried welding it first. I made my adapter plate and got most stuff fitted, all I have left is to cut the rod to length and drill the 2nd hole in it. I forgot to take pictures of everything. I ended up having to put the actual shift in backwards, had to cut up the shifter hole a little, and I had to drill a couple holes in the tunnel to get to the rear bolts. Pictures will make it easier to understand. I could have gotten away with just the holes or maybe not at all if the tranny's shifter was a couple inches further forward. I could have cut the same amount out of the tranny hole if I just used the camaro tail housing and stock shifter I think. I'm going to have to make a custom shift stick to get the **** where I want, the ebay stuff is usable right now, but with the bolt on shifter stick it'll be easier to frabricobble something together for better placement.
Oh I too ended up just drilling a hole in the back of the tranny instead of pushing the freeze plug out, I have to make a felt seal still. Felt will be fine for this.
Miata input shaft to bellhousing flange offset (from tim): .410"
Length from input shaft tip to T5 flange (on a shorter input shaft box): 7.189"
3/8 transmission flange (1/2" flange, milled down an 1/8th for flatness): .375"
So the total miata bellhousing needed is: 7.189+.410-.375 = 7.224"
Wow, thats really not a lot of bellhousing lol.
What I screwed up:
The t5 input shaft must be shortened. Otherwise it will interfere with the crankshaft. I do not know how much this needs to be shortened yet. But I will cut it so that the tip is at the same place in relation to where the splines start as the miata input shaft.
So the new length is 7.189-(amount necessary to make the t5 input shaft tip in the same place as the miata input shaft)+4.1-3.75 = 7.224" - antmttistitspatmis.
Based off of a measurement from a locust forum the miata transmission is 32" from bellhousing face to shifter pivot.
Subtract .410" gets you 31.59" from tip of input shaft to the center of the shifter.
The t5 transmission I am using is 26.7"-(the above amount taken off the input shaft) from the tip to the center of the pivot.
So my shifter must be extended 4.89" - (the above amount taken off the input shaft).
@Leafy, or @TurboTim do either of you know if that will interfere with the back of the transmission?
