This is on my 1989 ranger 2.9 liter V6 between bell housing and engine. Name? Dust cover? Index plate? Guide plate? Need to find one if anyone has leads?

 

Officially it is called a Block Plate, but AKA separator plate or spacer plate

It is used to line up starter motor so it doesn't shift around, also a shim since its there, lol,
I think 4.0l OHV used the same plate as 2.9l
If there was a different starter motor for manual trans and automatic for your year then Block Plate was most likely different as well

 

Thanks Ron,

I sure wish I could find one of these.
