1g tranny going into 2g?

[BKs50trimGST]

I am picking up a 1g tranny in the next couple of weeks, i'm buying it because its a really good deal and mine has 130k on it. If anyone has swapped a 1g tranny into a 2g I would love to know exactly what I need to do, I know i'll figure it out when I pull the 2g tranny but I would like a heads up on what to expect. I know I have to weld the 1g brackets in a differenet place or something like that, so if anyone is or knows of a decent welder and good prices I would love to know. thanks again.. and the reason why a 1g is going in is because its TurboTrix and I need it for the power that I will be pushing.
