Sorry, can't give you advice on the 1gn IM removal, other than there are about 10 bolts holding it to the head, vs what 5 on the 2gn. The 2gn IM bolts are 8mm heads IIRC, but IDK what the 1gn's are. I got my IM on ebay, so the hard part was done as for removal...
Just take a reasonable assortment of wrenches, sockets, a swivel joint for the sockets - can't hurt. Various extensions, etc. Hammer/vise grips/duct tape.
Edit: Oh yeah, that case full of cash, under the back seat, it's mine. I'll PM you my address.

Patience, of course, is a very powerful weapon, but sometimes I start to regret that it is not a firearm.
Too much time spent here is a sign of a bad case of Ownaneonvirus.
