I also have a blue 2.4 that I got from Gary back in the 90's and blue 3.2 I got around 2002. The 2.4 looks exactly like the one outssider has in the picture.
Look at the exhaust bolts, if they go straight across it's a 3.2 but if there staggered it's a 2.4. thats the way mine are anyway.
Try to PM rcign, if anyone would know it's him.
