The "interference fit" method I've seen and experienced is...
1. Apply a shitload of heat on a ring gear, (preferably with at least 2 blok=
es dressed like blacksmiths), with strong steel tongs to lift a ring gear th=
at could burn a hole through your garage floor...
2. Which is then dropped/ slipped  carefully over...
3. a near frozen flywheel...
4. lightly tap the ring gear into a square position on the flywheel.=20
5. follow up with a couple of appropriate tacks from a MIG.=20
6. Omit step 5, If you think you need to replace the ring gear in the next 1=
50,000 - 350,000 miles, and don't have a spare flywheel.....
Trust me. You will replace the flywheel before you replace the ring gear aga=
in...=20
Lots of heat. Placed on lots of cold. That's the definition of an "interfere=
nce fit"=20
Tack weld if you don't think you got it right. Just to be sure.....
Just to be sure.=20
