Belltech 5353 springs

[chevytoban]

I recently purchased a set of rear drop springs for my 69 -910 and I'm having issues with fitting the bottom spring retainer. I'm using the 1"spacer on the bottom as I purchased the kit for a 3"drop rather than a 4" My problem is that when I go to install the factory retainer (Ive ordered a new set)the lower spacer which comes up the middle of the spring and interferes with the retainer placement. Anyone else have this problem. Thanks in advance
