I'm the previous owner before laotsu. Glad you are taking care of "Blue."
She had a LZ22 when I bought her sometime in 2004-2006 and an S-10 stock seat. I personally found an original 521 seat, cleaned it and painted with Rust Doctor, then painted it, and recovered and new foam with a custom seat cover (about $200). She was good to me, but I had to upgrade. I like what you've done so far. I had plans, just not time. Those fenders are from a 72 that my friend painted for me because the original were not great around the headlights. I may have some parts from the 72 if you need anything. Let me know if you have any questions, I know most of the history of Blue. That L16 engine and tranny came from the 72 also. Had a 240Z wooden shift knob. The original transmission was noisy in 4th but still worked. I still have the LZ22 that was in it when I bought it. Sold her for way less than I thought she was worth, but wanted to see her go to the right home and I think she found it. Want to sell that old license plate frame?
