Whats the best way to get the upper tranny mount bracket off of the frame rail?

It's currently an auto and I need to put the manual transmission one in. It'll be tough to get to all of the spot welds for drilling, whats gonna be the best way to get it off?

Workin on a 95 coupe

 

a hammer, a crowbar, and a grinder if you dont have air tools.
if you do have air tools....then I assume you would already know which one to use.

 

the air hammer wont tear the frame up?

 

air chisel...if ou can get it right at the seem, it will break the tack welds lose, then all you have to do is grind the tacks flush......you can also drill out the tack welds and then grind down flush as well.

 

why do you need to take it off? Mine is still on and no problems at all.
