H4 H7 Light Bulb Combo On A Cutlass Euro Clip Question?

[HOMEGROWN IN THE 760]

I was told when putting a Euro clip on the older model cutlass you do not need to swap the headlight wiring harness to the 9004 bulb sockets, but that you could just use the H4 H7 bulbs that fit right into the original older model sockets, I was able to buy the bulb's but i am having trouble finding the proper retaining clip or bulb clip to hold the bulb in place. Is anyone currently running these bulbs on thier euro clip and if so what do the retaining clips look like? and where can I buy them?
Any info is greatly appreciated.
Thanks in Advance...

If you use H4 and H7 bulbs you will have to use a harness with relays, or you'll burn up the switch. Kirban Performance sells them for $68. Good quality relays and sockets.

you can buy relays for a few $$$ and wire them in. If you're not sure how to do it there are wiring diagrams all over the internet
