No, I don't HAVE to have them. I just wanted to locate replacements for the FULL RESTO crowd. Looking to boost my meager COVID income. Also think that 2021 small batch chrome will look better than new 1975 mass produced chrome. 

To airbornesilva:Top of spring is smaller I.D. than bottom. Spring O.D. is larger than original TF spring. Would not work on stock TF body. Not a viable replacement.

To msavitt: You are lucky to have a pair that could be " saved". I have never tried EV. I am looking for repro springs because the useable supply is drying up. parts-traders is selling repro springs for the Pre-TF bikes. Measurements show the springs are smaller in all dimensions than TF springs.                                                                                                                                                                                                     P.S.: There is currently a set of new NOS Thermal Flow shocks on EB. They are priced at $ 499.oo + $125.oo shipping from Singapore. Hmmm...    I have a brand new pair too. Well my shipping will be cheaper.                                                                                                                                 

I was skeptical of evaporust and didn't use it with dt360 resto, which was aesthetically a pretty clean machine. My DT1E on the other hand was crusty and rusty and beaten to hell. I thought for sure evaporust couldn't help, I was wrong this crap is magic. Key i found is a through cleaning in BBQ lighter fluid then soak in evaporust. Come back in a day and brush with plastic bristles and soak another day if needed.   Once 250 is done I am going to kerplunck some 360 bolts and fittings 

if finding new vs cleaning is your thing that's cool, I am sharing so others who doubted that moderately rusted parts can be saved.

Update   Update
I have found a source for the manufacture of chrome stock replacement springs for Thermal Flow shocks. I have not ordered any yet. They should cost around $ 250.00 for a pair plus shipping. Please let me know if you are interested. Details are being worked out and, depending on feedback, the initial run will be offered to forum members first. Send questions.
