I have found out that it is a late type Scorpio diff house (frog eyed scorpio ) and it wont fit...
Been told by the company that I should just cut away the ribs to make it fit....anyone have a opinion on that ???
Personally I'd send it back and have THEM do any modifications, as they've cocked up. Presumably they asked what it came from when you sent it in? If so, they should've repaired/refurbished it accordingly.
