Moving right along on the Bronco, and I've come to the first major compromise.
The input shaft on the Toyo trans had some scoring where the pilot bearing spun. While researching bellhousing options, I noticed that the '85-up bells with integral slave cylinder mounting were much more common (and thus cheaper) than the '83-'84 external slave version. The transmission input shaft length changed between the two options also, the later version about an inch shorter. So by going to the later bellhousing, I could fix the issue with the galled input shaft, as it will need to be shortened about an inch. I bought an integral slave to make sure it would work with the older style Toyo 4 speed, then ordered a late bellhousing from a Utah wrecking yard ($60 shipped).
So, first picture is of the input shaft, which will have to be shortened...
And the slave cylinder. Bad part of this is the trans has to come out to replace these, but the good is the quill and throwout bearing are part of it, and get replaced too...
Speaking of the quill, the Toyo quill has to come off for this style of slave to fit. So off comes the front cover for a little cutting....
Had to file the ears of the slave slightly, as it gets pinched between the transmission and the bellhousing, but it fits. Bolted it together, just have to shorten the input shaft once I get the correct measurement.
This shows the excess length of the input...
Last update is I've abandoned the baffle idea, because I stumbled across a windage tray from a Toyota V6 application that I can modify for the 2.3L.
Needs some trimming, but the bore spacing is close enough.
