i got a set of headlight lamps from laurel mountain mustang and i am tring to put them in my 1990 notch but the turnsignals have the bolts in such a hard spot for me, im using a gear wrench nowew i could get at the top 1 but the bottom bolts are a pain, not sure if the radiator would be a problem b/c its a very large aftermarket 1. any tricks to this that im missing? ps. i have big hands so its hard to move around in there
