Did you try a search on www.car-part.com for a used spindle?
That site runs off the same Hollander Parts Interchange Guides that the salvage yards use....I would assume the spindles would be the same 73/74 but you have to call the numbers listed and ask them.Andrew K said:I just went to that site and I found a bunch for '74, but only a few for a '73. The ones for the '74 were cheaper. Are they the same spindle or did they change in '74.
THANKS
