Thompson power steering pump serpentine pulley?

[harleyabarton]

alright I've got a 66 U14 that i'm putting power steering in I've installed the steering gear box and steering shaft (swapped it from my 75 which i did a FULL restoration on) basically I've got a 302 or 289 under the hood but when i bought it it came with a serpentine pulley set up. id like to use the original Thompson pump from my 75 to power my 66's power steering gear box. my issue is finding a serpentine pulley for my pump. does anyone know a vendor that sells serpentine pulley for this pump or at least no the pulley shaft size of this pump so i can find or fabricate my own??

also if anyone has or needs advise for fitting the steering shaft in a early 65 (66) let me know Ive already down it ahahha.

I don’t recall now which junkyard vehicle mine came out of, but the “5.0 serpentine” pulley on my Thompson pump has the raised-print marking “E57C-BA” on it. It fit the Thompson shaft perfectly.

I’m not answering either of your questions though. I should write what vehicle I removed the part from, on the actual part, for better record keeping.

Wildhorses4x4 and broncograveyard mention the Thompson shaft size as around 0.685”.

I found this plastic pulley (I believe my Ford one is also plastic) on summit: https://www.summitracing.com/parts/rnb-300-028/.

There are some pricier billet aluminum ones too: https://www.summitracing.com/search...lley-bore-diameter-in/0-685-in?ibanner=SREPD4
