Can someone tell me how the turn signal indicator comes apart behind the dash of my 69? I need to change a bulb. I tried pulling it apart, but it won't budge maybe because it has been together for 50 years. Where does it come apart to expose the bulb? What size/type bulb is in there?<div id="yMail_cursorElementTracker_1579627662354">Mike MacLean<br><br><div id="ymail_android_signature"><a id="ymail_android_signature_link" href="https://go.onelink.me/107872968?pid=InProduct&c=Global_Internal_YGrowth_AndroidEmailSig__AndroidUsers&af_wl=ym&af_sub1=Internal&af_sub2=Global_YGrowth&af_sub3=EmailSignature">Sent from AT&T Yahoo Mail on Android</a></div></div>
