Are all 4g64s created equal?

I was wondering if all 4g64 blocks are the same. I'm in the market but I'm weary to use one not from spider. Thank you.

I did more specific searching and found my own answer. Sorry rookie move.

No, they're not all the same. At some point they did a complete 180 (turned them around).. Some people theorized it'd still work, but I think they're insane. For Eclipses it was 2000, for Galants I think it was a bit earlier but I can't remember the actual year of change.
