I don't know about SRT's but your hubs should be 32 splines. Open 215 cast iron diffs inputs are 30 splines.

Commonly, when one goes from open diff to getrag the hubs are the same but axles are more robust and have different spline count. Cannot swear but 27 splines I believe.

You need a longer bolt for the forward mount.
