looking for advice on front shock insert replacement, brands etc- car is a 75, Options

[DRPHIL914]

so i realized that my front shock inserts are close to 20 years old according to previous owner records and i didnt replace them when i did my rear suspension upgrade . I have sprt bilistein in rear with stock sway bar and 100# springs, pretty stiff compared to front now and 5 lug fuchs, 205/55-16’s front and rear.
when i did the new front bushings etc and the turbo tierods i did the stock calipers and drilled 5 lug stock rotors from PMB , but left the strut inserts alone, but now 3-4 years later i can see one side is about 1/2” lower tto so before getting into the alignment proceedure i figured its time to get new struts inserts so,
what brand ? and who has the best deal? leaning toward bilisteins too but what is the proper part number? and should they be “sport” to match rear?
i have stock sway bar and will be putting on the new Tarrett drop links i got from group buy at Okteenerfest

so take the yellow sport B’s off rear and sell them?
anyone want a trade?

thanks for the quick response, Mark. I will start looking in that direction.

front needs to be adjusted too, its lower on right by 3/8”
and a bit more at fender and frame spots i measured from, could be partly due to the strut insert going bad a sagging more , but could also just be at the A-arms too, i have mever adjusted those. when the turbo tie rods were installed i had just done the a-arms and all the bushings and bearings and brake calipers etc and took it to Bob Woodman tires, an expierenced porsche perfomance shop to have them install the tie rods and do the alignment and didnt give it another thought, but it needs to be rechecked i think.
