Yes, there are 4 bolts that hold it to the trans to the trans mount and 4 more that hold the mount on the cross member. If you take it apart in the middle, it would be messy and I guess take some weight off.... but at some point you'll need to get the input shaft and bell housing off..... I say get a strap and put some tension on the trans, then get a BFH and go to work around the bell housing. Maybe use a block so you don't break it... But it's yours, so do what feels good.....

If you're 128% sure all the bolts are out, then my guess is the clutch disk is rusted to the input shaft, or the pilot bearing is seized to the end of the input shaft. Either way is not going to be fun to get out.... Try the strap and hammer first....
