NV3550 Installation Question

[mnido]

I am putting my Bronco back together again after my 331 Stroker went south. My new install is a Blueprint 347. I thought I recalled there was a bearing that went into the flywheel which matched up to the output shaft on the NV3550. However there isn’t a bearing in my flywheel which I had resurfaced. Is there such a bearing ? And if so where can I purchase? Thank you !

its more a bushing than bearing inside the flyuwheel , this is an example but not the right one https://www.google.com/search?q=fly...8643010875789533,pvt:hg,pvo:3&oshop=apv&pvs=0

It goes into the recess in the back of the crankshaft. Light press fit.

I feel like bronze bushings hold up better than needle bearings. I've never found an intact needle bearing when doing a clutch job.

If the snout of the input shaft is in perfect condition (new transmission) then roller is fine.
If the snout is less than perfect, has wear, the bronze bushing is the better choice.
