I've been known to take a bench grinder to custom make odd tools... had to change something on. 90s Caddy for a Friend's Mom ( RIP Shirley Hinds, got jab 5 days later, gone) cut the wrench down, and narrowed the opening, otherwise, it was pull the engine up some. May have been a Northstar, I don't remember. All I remember, was a bunch crap all in the way. Water pump, maybe? I dunno
