Vacuum advance

[Rick68]

My vacuum advance came in and it is the right one.It is the AIRTEX 4V1053 and it is stamped B28.Opens at 4"hg and stops at 8"hg.I ordered it from Amazon and had it shipped to me in Canada for $21.64.The part itself was $4.99.There is still lots on Ebay and Amazon and ROCKAUTO.If you order from ROCKAUTO make sure you use 1973 Caprice/Impala 350 2 bbl because if you use 1973 Camaro 350 2bbl it will not come up.
