I recently ordered a set of Headers for my 80 bronco 4x4 with a 429. I got them through Jegs and was very pleased with them they were helpful and friendly they said my headers would be here in 3 days and sure enough they were there in 3 days i got them for an 80`s f350 4x4 with a 460 there long tube headers but they bolted right up with no problems so if anyone needs any for there 80`s bronco check them out heres a link but they worked perfect and if anyone wants to know about jegs ill definatly be useing them again they even sent me a jegs hat and stickers http://www.jegs.com/cgi-bin/ncommerce3/ExecMacro/headers/header_dsp.d2w/report?prmenbr=361&prrfnbr=8268&partnumb=520-6911&cartype=FORD+/+MERCURY+F-250,+F-350+(4WD)&vendor=FORD&header_type=Competition
