Mini starter issue

Looking for any tips to installing a mini starter on my 69 440 w/727. I bought a mini starter for my Barracuda. When I tried to install it, the dang gone thing hits against the block keeping the bolt holes from lining up. I bought it off of fleabay to save a buck, it may have bit me doing so. Is my only option to return it, or is there any tricks to make it fit?
Thanks,
Andy
