I am trying to find a NP435,flywheel and bellhousing for a 390. It seems all the yards had tons of them a couple months ago but now nothing. I am willing to take a drive so if you know any yards that have them let me know.

 

I'll keep my eyes open Mike.
I had a set, when I converted my F250 to a 460 from the stock 360 FE, but have since gotten rid of it. Oh well...
When I get a chance, I'll check the local Picknpull for ya.

 

Mike, I have an NP435 in my truck that I'm getting ready to pull and replace with a T-19. It works but needs new bearings as it's pretty noisy. I also have another with a bad 1st gear, so if you're willing to go through one or both of them, we could work something out. I rebuilt my bro-in-law's 435 a couple years ago, they're not too bad to work on. I got a kit from Bronco Graveyard, one of the site sponsors. The deluxe kit goes for 98 bucks while the master rebuild kit is $165.

Flywheel and bellhousing won't be available till I pull the FE for my 5.9 swap however.

Either one of my local yards should have what you need, however. Both have a good supply of bump and dentsides. If I have time (which isn't too likely right now) I'll try to get over there and check it out for you.
