Many discussions on the board in the past. Try the search feature. The general idea is to get spark to your plugs...from what i hear, plugs dont care that much about brand names
the early year (1974) STOCK wires will work great from what i hear. I bought the standard stock wires from Pelican that work great for my year (1978) which should be the same for yours. I think it was tad bit less than $180
The big problem is not the wires ( i think) but the BERU connectors. I have read about several guys here building their own wire sets from over the counter bulk wire.
Most of the discussions discount the need for the grounding straps.
I would just go with stock, either the shielded or unsheilded. if money is an issue, look into fabricating your own. The aftermarket wires are quite expensive.
Good luck.
