Any tips for installing a small cap Hei on an 86w250? Did you use the one from KMJ performance? Just got mine and the instructions are worded like you've already got one and you're just replacing it. I've got the dual pick up dizzy now. Just wondering what all you had to do to install yours since you've got similar truck. Mines a daily work vehicle so looking to save any unnecessary down time. Thanks for any tips you could share
