power windows available in 73?

i put power windows in my 71 240z , they were made by SPAL, but it wasnt an option on the original, i didnt like the switches that came with it so i used factory zx switches,and mounted them were the ash tray was , came out real well , also put in power locks that was a tricky matter no room! but they work perfectly, i wasnt inpresed with the button cover ups for the handles eather ,but i havnt had time to re-skin the doors yet , but the SPAL kit goes in sweet and easy!
