OK here goes nothing. I managed to acquire two D5 & two D9 bellhousings. Yeah, it was pricey but I needed 2 of them & it was a package deal.
 
I have one of the D9 forks & I know any 5.0 fork works so I'm good to go for the 2nd one. The problem is going to be the missing D5 forks. I know they are specific to these bells.
 
 I also know the part number for them is D5ZA-7515-BA but what are they out of? Are those just standard Pinto/MII forks?
 
If I can get the right D5 forks I'll probably use those & sell the D9's off. I also have a spare bellcrank bell housing now that I wont need. I've still gotta pick up another T-5 but that's the easy part.

Great, a 1 year part. That wont be too hard to locate at all......
 
Uuuuggghhhh!!!
 
Well....if anyone has one or two of them floating around message me please

The way everyone closes the hole is by banging a small hole washer with a ball peen hammer to cup it & weld it over the larger hole. I have to do that to my 5.0 fork when the time comes.
