I'm looking to get a new torque converter and I've found that it's hard to find a BOP that's not to pricey. The converter I had before was a Chevy with threaded pads, and in the description on summit it says will not work with BOP, but it worked fine for me and I didn't know it was wrong until I just checked to see the bolt diameter. Now that I'm looking for a new one 3000-3200 stall the ones I've found don't have the threaded pads. Instead they have the nut and bolt Chevy style. One on jegs and one on ebay by assault. The assault one is advertised as BOP but I asked them if it's threaded or bolt and nut and they said it's bolt and nut. Will this work or does it have to be a threaded pad?

 

Either one will work. Most stock OLDS had threaded lugs. All my aftermarket stall converters are nut and bolt. Use grade 8 or ARP fasteners.

 

Oh and make sure they are fine threads.
