I recently picked up an early TA hood (with the off-center hump/vent) from the junkyard for $30, but there's no insulation or water-catcher stuff.

I might just get some insulation from a normal hood and make it fit, but I don't know how far up into that hump it goes or how close to the vent.

If someone could enlighten me or post a picture of it, that would be swell.

I already came up with an idea of sorts for the water issue.

i dont think you need that insulation i ran my 91 rs for over 2 years withought it and had no issues, i also didnt have the wwater catcher thing and still had no issues.
