I just measured the waterpump from the timing cover torwards the mount and it'* 8.25 cm. i have about a half a cm of clearance to my mount and i had to slide my mount away from the timing cover ALOT to get that pump in there. that was scary It fits but only my a half a cm on the L36. I can't take anymore measurements any time soon b/c it'* raining.

Zoomer is sure that the electric water pump will work on the series 1. and a guy I was dealing with from thrasher said he has used it on a series 1. As far as the water pump pulley, Zoomer was sure that it WOULD NOT fit. Electric water pump is pretty sure my next mod.

I had to grind down a small portion of my motor mount to get my UD waterpump pulley to fit...so we'll know why my mount breaks down the road.
Will it fit a Series I? First off we need to find out if the stock pulley for Series I and II were the same, then its probably a matter of grinding down the motor mount area closest to "point of impact", but I highly DON'T recommend this! I believe I am the first Bonneville owner to install the ZZP UD Waterpump pulley and I did it as an experiment to find out if the rest of us can get them to fit. It "fits", but not like I would want it too. Our engines move a lot more under sudden acceleration than compared to a GTP with its 2 dogbones up front.
As of right now I'm still testing the pulley to see if its causing any damage.

Emailed Zoomer last night about the size of the underdrive pulley and he said that it is 5.5" diameter and the stock pulley is 5" diameter...... so its possible that it could fit i think..... if nothin else theres always the lightened water pump pulley too
