best enclosure for this Goodmans 10"? Measurements?

Hello again!

Well i have at home a pair of new (to me) Goodmans 10" red alnicos.

I would like to build a cabinet or a OB for them, but i don't know in what sizes to do it...

Someone can help me with that? Has the same speakers?

I can't find any specifications of them on the net.

Is hard to measure Thielle Small parameters...?
I'm neophite on measurements, but i know an old guy that repair speakers that can help me with that i guess.

Thanks for your insights!
