Britt,

Sorry to hear of your distress.

Yes, searching out a replacement may be in order.

The two weak points of a 901/911 transmission are:
The strength of the cantilevered input shaft for 1st gear.
The “Simplified differential” in ’68-’70.

There is not much to be done about the input shaft except don’t stress it with excessive standing starts.

There are still a few cars that have the original “Simplified differential” that haven’t had the update differential shaft block parts to replace the axle flange stretch bolts with the teat on the end.

If you need to find another trans, this Forum has some experts to coach you.

Best,
Grady
