[Onefast99gsx]

Thanks Brian... Yes, i think the Yellow's are slightly smaller than the reds. Well i scoped it out tonight and as far as dropping the battery down onto the sub frame forget it, if you have a yellow top Optima, 2g 99 GSX. You're dealing with the right motor mount in the way, a high pressure line coming out of the firewall which is i'm assuming the a/c, and the fuel filter. I'll have to get a slim battery or move it to the trunk area as suggested. I'm not sure yet what i'll do. The cost will be about the same. The Odyssey's in Summit are about $120 cheaper on ebay but not sure if they are rejects or something. This manifold just got a little more expensive.. :-(
