My GM parts catalogue refereneces the same part
number, 336877, for both the HW and RW rear spring. The
"HW" and "RW" are the production codes. Whatever that
is and why they are different I don't know. They are
the same part. From the spring chart the 336877
spring is the stiffer of the two rear springs available
for H-Bodies but the chart doesn't reference the
Spyder suspension option.
That's all I know.
