Brief Answer:
I would return them
Detailed Answer:
Hi,
BC is nothing but basal curvature of the lens. Though the power details might remain the same for both the lenses with 8.6 or 8.7, fitting might be an issue.
It is like a shoe size of a brand fits you but the same size shoe of the different brand may not fit you perfectly. So the branded or templated BC of brands differs.
If you want a customized fit, you have to order them. I generally do not believe in the idea of ordering lenses online other than your optometrist.
Coming back to your question, Fitting a 8.6 instead of 8.7 lenses without the supervision of an optometrist sounds not a good idea. You may get dry eyes.
So you may want to return them.
Hope I have answered your query.
Take care
