1972 duster leaf spring ideas

Espo springs on back order for 1 to 2 months or longer , they have no time frame from there supplier , but offer 5% discount
That stinks. I bought my springs from Espo in December and had them by Christmas. Was very pleased. I wonder what happened that their suppliers can’t provide the needed materials. Their springs are well worth it though.

I have a bad feeling that a lot more companies will have indefinite backorder on parts as this year progresses...
