Arrow Changing blown motor out for OBS 7.3

Blew the motor in my work truck the other day so I am swapping in a motor from a 95. I know what I have to change to make it work, but what do I do with the hole in the valley where the fuel pump goes? Just get a freeze plug that fits in there? Anyone know what size by chance?

Thanks

Update:

A 7/8" freeze plug works perfectly. Smeared some permatex on there and it works fine.

Also something I learned was that the intake plenums on the 99+ have two more bolts than the OBS motor. So that means that there is no hole drilled in the head to put the bolts in. I just smeared a good amount of permatex on there and I think it will hold the pressure. I will try and take pictures to help describe what I mean.

Good to know...

I bought a '96 PSD long block motor a few years ago, just to have as a spare... for $300 I wasn't going to pass it up!

obviously, this info will come in handy if I ever use it.
