if you're still looking to modify those buckets, just cut them out completely and solder the wires directly onto your bulb terminals
i think the HID-style aftermarket bulbs are a lower profile too, if you need even more clearance
i'm pretty sure just cutting the buckets out will be fine though, you shouldn't need to modify the bulbs unless you're going for a six inch beam or something narrower
bulbs are bulbs
put some epoxy over the soldered terminals to keep the water out
but like i said, you don't really need to cut them completely unless you're going for a 5-6 inch beam or narrower
sorry man, you need to get your facts straight.
i've heard of headlight bucket modification due to extreme lowering jobs, but never bulb modification. if you can find someone who has had to modify their headlight bulbs because of a lowering job, i'm all ears.
also, narrowing is really the least of your worries with headlight bucket clearance. you could run a 10\" narrowed tricycle beam up front and still clear the buckets. it's when you start to go lower in the front that you run into problems. adjusters turn the leaf springs and the leaf springs turn the torsion arms up and that pushes the tire up into the fender and forward towards the headlight buckets. spindles will compensate for a few inches in the adjusters and bring the wheel slightly back to the \"center\" of the wheel well. 1 or 2 sets of caster shims should set your caster back close to manufacturers spec. and of course tire size is a big issue. and then depending on how low you are you have to be concerned with tie-rod to gas tank clearance and bump steer. but it doesnt matter if you're 4,5,6 or 8 inches narrowed, you should never have to cut the bucket out completely or modify your bulbs.
now back to drooling over mikes car. B)
btw mike, are you insured?
