Replacement spark plug boots?

[Black88GTA]

I need to do my plugs and valve cover gaskets soon. So, I went looking for new spark plug boots, but to no avail. Searching indicates that Subaru doesn't sell them separately, and you have to get new coils if you want new boots. I found a few threads with people who had the same problem, but no good alternates to OEM boots were located at that time. But, these threads were a few years old - are there still no boots to be had, or has someone found something since then?

There were some mumblings about a universal plug wire set with a single boot (for the distributor wire) that works, but it sucks buying a whole wire set for $40+ just to get one boot and then throwing the rest out.

I found a post where someone listed the dimensions - 1.5" length, 3/8" ID over the plug, 5/8" ID over the coil. With these dimensions in-hand, I searched all over the internet, but found nothing. Called MSD's tech line - they didn't have anything either. I fired off an email to Accel, but haven't heard back yet (and am not really expecting anything either).

Does anyone know if there is anything out there that works?
