MSD don't make a cap that fits, I've tried. I ended up getting an original dissy rebuilt & regraphed to the same specs as the MSD, coverted it to electronic pickup & hooked it into the white wire on the MSD box. The MSD dissy in my toolbox waiting for the next car that it will fit into.

looks pretty good to me mumbo there is 2 different sort of lead caps in the kit that i got might give the smaller ones a go before i start hacking into the shell

i emailed MSD in the U.S. about this problem and it says the cap of 8437 fits this dizzy and has about 1/2 inch lower difference but is a standard leads end cap might be worth a try as well

The difference between the HQ and Torana engine mount plates may be enough to make the dizzy fit with one but not the other. Which engine mount plates do you have mumbo?

Don't suppose they gave you the part number of the different cap?

Here's how well mine fitted. I think I had HQ mounts at this stage. Torry mounts didn't really make it any better. When they say std leads I assume that this style of lead connection isn't std. Correct?

Well that would work then. I think I had better track down another cap. I got another one but I can't remeber what the part number was. It's now 180 ks away in storage. I'll try to track it down when I'm next there.

Can you buy a flat cap for these with the leads coming out from the sides?

Mine has the same cap as yours so it must be the engine mounts my engine seems to sit ferther forward.
My dizy is not under the lip like yours it just in front

I'm sure it was HQ mounts at this stage. The Torry mounts made it worse as they lifted the front of the motor, which made the extractors fit... That rear lead terminal was only a couple of mm away from the firewall lip. That crab cap would probably work ok. I don't have picture of the dissy from the side.

If it was mine i would gently tap the lip back you could make it look factory and you prob would not see it anyway

Mumbo, In the picture it looks like the gutter has been trimmed off the lip on your car. This would increase the clearance a small amount.

Another possible cause of clearance issues is the angle of the engine. The engine angle can vary considerably depending on gearbox and crossmember choice. It may be the engine is lower at the back on cars with clearance problems which would cause the dizzy to lean into the lip. A spacer under the gearbox mount may do the trick.

You are probably right Andy. My tremec can't go any higher, I have tried. All it needs would be to have the rear of the trans lifted 10mm, that would make all the difference at the dissy.
