Quick note on the Accel ceramic plug boot wires. For the vortec dizzy, they only sell straight or 90* sets that plug into the dizzy. straight boot #5 plug wouldn’t fit with the jba headers, #3 fits but right against it. I got a single 115* ceramic boot/wire cut to fit kit to replace #5. The kit only has dizzy terminals for hei or points dizzy. If your very careful and take your time, you can disassemble the vortec dizzy terminal boot and terminal end, and mate it to the end of the 115* or 135* booted wire. be patient, very small screwdrivers, picks, needle nose pliers, crimp tool, and a hog ring plier were helpful in getting the original wire off the terminal and shaping it to fit back into the terminal and sleeve in the boot. Close to pia, but doable, else you have to buy a full set of 90* wires to get 1 or 2 wires to replace the straight ones that are to tight.
