1967 Corvette 327 Powerglide Accelerator Spring Genuine GM 3904245 NOS
CAVEAT EMPTOR: this is a genuine GM spring made in the USA; no imported. These were purchased in the 1980's when we were collecting samples for reproduction references. Factually some look my look shabby with faint chipped paint. That is the reality of many GM parts sold in service. By comparison, a repro spring must look perfect with bright paint. If the repro looked as poor as the OEM; nobody would buy it.
TIP: if you want a pretty spring: repaint it - it will not effect anything but the appearance. If you want a repro select 3459206. Photo may show multiple pieces, however the unit of sale is one piece. Also used on 67-68 Camaro Powerglide with 4 bbl Rochester carb; 67 Chevelle, Chevy Powerglide except 2BC or Sp.H/Per
