Delta 2600, Help with shower valve please

[SouthernTester]

We are renovating our master bath. We have a Delta 2 handle shower valve that we would like to reuse if possible, really like the less flow restriction that comes with 2 handles. No numbers or letters stamped into the valve assembly. We reached out to Delta support with the same pics I've included here and they said the valve we have is the 2600/2800 series. When we search for that series we find 3 handle valves rather than 2 like ours. They did provide replacement numbers but they don't seem to match either. Response from Delta - "The following is a parts breakdown for your 2600/2800 shower unit. The two small "xx" following some of the numbers are for your choice of color, bronze. The yellow bronze is CZ, and the brown bronze is RB. RP18276xx (x2) escutcheon, RP18136xx (x2) sleeve, RP18627 (x2) extender, RP1740 (x2) stem unit assembly, RP4993 seats & springs. Tub spout options: RP5833xx non-diverter, RP5834xx diverter spout. Any shower arm, shower flange, and showerhead of your choice. "

We were hoping to find an oil rubbed bronze kit to upgrade our current valve. Any chance of this?

A two handle faucet like that is no longer code legal unless you have a way to temper the water to prevent scalding.
You have the two handle, so just ignore the center diverter in the picture.

Thanks for the info. We ordered the H215 handles as replacements but they don't fit the stem (extender). The one we have has a "D" shaped end and the H215 handles have more of a rectangle shape they fit. I have included pictures of each type. If we could find the series or model of the handles that fit this "D" type it would really help!
