Help: I have Spark plug wires questions....also Radiator w/fan question?

Hi all,

Just installed JBA headers on my 67' mustang w/ 302.
The spark plug wires i have on it are straight 180 degree at the spark plug end and 90degree at the distributor.

What is happening is that the boot is burning up against the header.
I need to find a set of wires that have 90degree boots at both ends so that it will clear the header and not touch the pipe.

The problem is where i live the local auto parts store is not helpful or knowledgeable at all.

So i'm trying to decide/find an exact part number that i can go in and order.

Couple questions i have:
1. do i go 8mm, 8.5mm, or 9mm?
2. how do i determine what type of connection at the distributor i have male or female?
3. I've read that making the custom length wires do not last as long is this true?
4. I've read that Ford racing wires are better than msd when i comes to the ford application, is this true?

Regarding Radiator anyone know a good radiator w/fan combo.
My radiator is toast and my dad was saying i should go with a fan on the radiator so as to take the fan off the engine.

Lastly I'm located in victoria, b.c canada and so awesome places like Summit we do not have.
We have Lordco=crap service.

any help would be great.

Most Ford small blocks I've seen use 45 degree boots, but you can use 90 if you want. The link below is for 45 degree. If you search some more on Summit's site, you'll find 90s. I did a quick check about Summit's shipping policy, and they consider Canada NOT a foreign country. Go figure. :)

Custom length wires get a bad rap because the person making the connections does a bad job. Find someone who has made a bunch of sets, and you'll get a good job done. I made mine and have had no problems.

Using the engine driven fan is about as simple a system as you can get. It works and has only one failure point: the belt. These work well. If you replace the radiator, and have a properly fit shroud, you'll cool just fine.
