Need help finding a core. (200-4R) Its either pay $650 for a core charge or buy one outright. I figure that I can save some money if I find one, but finding one is going to be the trick. The particular 200-4R that Im looking for is hard to come by. If I decide to buy one myself, then thats the tranny that will be built. Ive been looking everywhere, doing numerous searches and I havent come up with anything. 
I figured...where can I get help...hrmm, where else but 
LS1Tech! 
Ive also checked Ebay, but theres only one thats on there, but isnt what Im looking for. Im looking for one that came out of a 84-87 Monte Carlo SS or a 84-97 Grand National. If anyone has any suggestions, ideas, sites, etc., I would really appreciate it. I finally got the money to buy the tranny, 
now I just gotta find one. 
Thanks in advance!

Re: Need help finding a core. (200-4R) Why do you want one of those? Once it's rebuilt, the internals are all different anyway and the dimensions will be the same. I don't even think the GN used the same one the Monte got, for that matter. Maybe it did, but I see people talking about GN specific 200's and they don't seem to include the Monte in their conversations. I was told my own 200 was from a GN, but I have not seen any evidence to prove it... The tag was removed when I got it. I've also been told there's a casting number in the housing, but I've been told there isn't, just as much. I can tell this much though, the tranny holds up with the right parts inside it. These rebult 200's must be getting expensive with a $650 care charge... Man, that's up there. Oh yeah, try www.turbobuick.com or maybe www.gnttype.org and you may find good results.
