I purchased a electric wiper motor that I think came off a 55-57 Chevy. Part number is 5047906 is this the correct motor ? Plans are to swap out the vacuum unit for the electric motor on my 55 Olds, this is supposed to be the easiest conversion.... Thanks Tedd

 

Pretty weird - 55 + 56 Chevys had vacuum motors, for sure!
Don't know about 57's though.

 

Don't think so, this has been a common adaptation for years.

 

Check out "New port Engineering", they have wiper conversions.

I had one of each - 55+56 = was wonderful when the blades stopped under acceleration!!

 

With a google I find both electric and vacuum for 55-57,seems strange that they would have both varieties being sold at the same time....Tedd

Thanks 64 Rocket for the lead, if this doesn't work out I'll go that route....Tedd
