Nearside lower suspension arm replacement on 1.2 auto - HOW do you do it!?

Hello all, I have just replaced the offside lower suspension arm (bought a pair from ebay for £36 delivered!), a bit of a struggle but not too bad. When I came to the nearside, the forward bolt would not come out as the end of the auto box is in the way. I tried carefully jacking up the box but not enough room... Do I need to drop the subframe to get the bolt out please? Thanks.
