Gen 1 and gen 2 radiator compatability

[tmontague]

Does anyone know if the gen 1 (echo) radiator will fit on a 2nd gen yaris?

I would be using a first gen fan shroud as well as the upper hose so it fits but I'm curious as to dimensions as well as the pegs that hold it into the top and bottom support beams.

I've searched online and it appears that the dimensions are very similar but I'm curious if anyone has actual experience with this.

The reason for doing this is Mishimoto and another no name company makes a dual core all aluminum radiator for the first gen's but there is nothing available for the 2nd gen's. My coolant is hovering round 230F each track session and that is with 90% water and Amsoil coolant boost, so time to upgrade.
