Just because you call something a repeater doesn't mean it is.
A simplex repeater is not a repeater due to two things: 1. It does not
simultaneously retransmit, and 2. It transmits on the same frequency.
Point #1 was just clarified by the FCC Monday, but point #2 has never
been misinterpreted
If it was originally a 450-470 MHz model, it will work fine at 444/449
without any modifications. If it was for one of the other bandsplits, then
you'll need to re-do the harness if you want it to meet spec.

Simplex repeater being somewhat of an oxymoron, I believe the proper
