340 main caps

And then, you end up cutting the crap out of the cap if you can't move the cap far enough to get some materiel so you can get the mainline back in.

That's why if you need to replace the caps for whatever reason, you'd better have a bunch to screw with to make sure you have some options.

Or just buy new caps that are far enough undersize so you have something to work with.

I used to save every cap off every block that was broken just so when the need arose, I had something to work with.

Brutha I hear you, exactly...and that's why I told him get a few sets of caps and find the ones that fit 'the closest', that only require filing/cutting the register and staking/sledging the iron over 'to the cap'...milling the caps sides would be last on the list after all else is exhausted. I had a 360 get line honed and studded one time ..and when I got it back the Caps didn't snap in...they just fell in then I checked'em with a bore gauge n was not happy ...some twisted .0003-.0005 I fiddle fkd that cap set for about 2 hours, torque n check torque n check
...and finally got it to where I'd call it perfect.
Something the op will need to do once he gets the caps to sit down in there..
