Laying it back helps at the top (for now the rad's just in place to hold the hood up)... at the bottom I need a bit more space. I think if I can get the rad to move back about an inch at the bottom I'll make it. The pipes that are in the way are just plumbing. I haven't taken one off to check but if it's a flaired fitting, it's a one hour fix. I may be able to shim up about .5" also.
If I could just relocate the rad's left bracket it'd be a snap, but the bottom tank is the problem. I wasn't counting on this.
