Hey all, I've got a 95 Eldorado, been a great, reliable car for me, for bout 15 years. Has 248k on it, and I think the exhaust cams are worn down. I read where up to 99 will work but does that mean that any and all, up to 99 will have the same motor mount holes in the block and have the same exhaust down pipe bolt-up? Car has a rebuilt front and rear suspension and rebuilt tranny. All It needs is another low mileage engine for me to put new headgaskets on, and install. Need to know what years will work, with no modifications. I read Jake's write-up on interchangeability, but I'm too dumb to figure it out, for sure. Thanks All!
