You'll have to do it though the passenger side wheel well with the wheel and plastic splash guard removed. I'm fairly certain you have the same type of balancer as a Series 2/3 which requires a 3 bolt puller. You'll want something like this tool. Just be warmed that the larger universal kits usually only have 2 out of 3 bolts you need.

Also, the bolt requires serious grunt to break loose. A good impact wrench is your best bet. And as was mentioned, look in to the bolts you need. Every time I see reference to a universal kit being used, they indicate that they had to buy bolts for it too. I bought my puller from rock auto specifically for the 3800, and it got it right.

Also be careful with the crank position sensor alignment, as it's adjustable.
