yo BW,
Congrats and Welcome.
Here is what I do to search for parts;
I use
http://www.fordparts.com
go thru the drill
copy the Ford long version part number or the short version. and then do a google with your year such as "81 Bronco distributor
I try to get the Ford Motorcraft parts via AMAZON; they are VG at delvy and esp pricing; I bought a $150.00 Motorcraft DPFE Sensor for $50.00 with free shipping and no sales tax; Local dealers wanted 150.0 + sales tax
same price & discount for an Idle Air Control (IAC)
