I don't remember any challenge putting the bolts through the bushings. I may have used the nuts as a press. I can't remember....so it must have been easy 
To get some room above, if you can lift the engine just enough (about 2 centimeters) to get to the stock height relative to the cross brace you may have the space you need to work with the bolts. But it may not be a good idea to flex tired and cooked mounts if you plan to leave them be for awhile.

Ok thanks guys. I've got them in. Ran through them with a 10mm drill (25/64 non metric not easy to find in UK without an online delivery). They are still a tight fit even though the holes were drilled out a little so I reckon I'm good.

Only tips I can give is make sure the insert holes on the rack are cleaned/sanded out a bit and greased when inserting the bushes. Use a long bolt and two washers and a nut to press them in, as suggested by Adrian. And then if you find you need to then drill the holes in the bushes out a little. No big deal.
I'll follow up when I get the car on the road and see if I notice any difference in the steering.
Cheers

It seems I had more problems than most so may just be the mechanic. I don't think failed motor mounts helped.

So far the Volvo mounts are holding the motor in the same position (top of intake just slightly above top of support bar) since about a week after installation, and isolating engine vibration very well. I've had them in for almost two years.
There was a night and day difference in steering precision and accuracy after installation of the Delrin bushings. The old bushings were not completely shot, but I was doing the MMs so it was a good time to replace them. I'm sure new OEM bushings would have been a nice improvement as well. Oil had softened the original bushings.
