Dick,

You want the answer for lossless or real components?  For lossless components starting at the generator a shunt capacitor of 831.93pF and then a series inductor of 269.96nH to the load will match to 25.67 + j18.68.  There are many more circuits that will achieve the same match.

This calculation can be done in just a few seconds with a free program like SimSmith.  I have a YouTube channel using SimSmith to solve all kinds of ham radio and RF topics if you are interested. https://www.youtube.com/channel/UCKSyLSu4fm_1RHoO3Jvk4YQ?disable_polymer=true

Is this what you want?

I did a quick Google on this,

I want to match a load with
the following characteristics:
Rs=25.67
Rp=39.26
Xs=18.68
Xp=53.96
To a 50 ohm source at a fixed
frequency of 3.725 Mhz.

Can someone point me to a
calculator that will give L & C
values I will need ?

Tnx, Dick, W1KSZ
