Here's a few photos I took yesterday at Midwest Cadillac Repair/Palatine,Illinois.
I haven't gotten the car back yet and the proof,of course is in the pudding, but these guys have certainly given me the impression that they know what they're doing. They dropped that engine in about four hours and address not only the h/g issue but other things such as replacing gaskets and seals that are easily replaced with the engine out.
I asked Joe how many NorthStars he's done and he told me that mine was #55 since October.
On the lift next to mine was another '99 with 69,000 miles that they were just starting.
Cost is less than half than prices I've seen from other posters that went to Cadillac dealers.
I found out about Midwest from one of the major posters on this site.
I don't know if he'd want me to use his name so I won't.
They're definately worth checking out if you have the dredded H/G virus or just keep the number handy if you don' have it yet.
