Anyone that has used these on a 4WD OBS, I sure would appreciate the benefit of your experience...

Two questions.

1: Dirty Dingo says to leave the bracket to engine block bolts loose till the engine & trans are installed to allow for proper alignment. That makes sense, but how hard are those bolts to get at after mounting? Is this really feasible?

2: Dirty Dingo says that the front crossmember needs to be notched on the 4WD. See the last descriptive paragraph on this page: http://dirtydingo.com/store/product_...oducts_id=1367
However, what the hell? I see no crossmember there???

Thanks for any help!
