I'm going to call out a great analogy when I see it. I can imagine perfectly how it would sound. Memories of my grandparents house in Montana came roaring back. Thanks for taking me back in time a bit and putting a smile on my face.

hehe no problem. that's exactly the place i heard that same spring strumming: grandparents' house, minnesota, with mosquitos streaming through the door as younger cousins stood there holding it open for no reason, trying to process why we were yelling at them to close the door.
in terms of length, the spring i ended up with is about 3-1/2" long and about 3/8" coil diameter. i wish i had the PN but i do recall they had a couple available as kind of off-the-shelf all-purpose springs, and this one had the lower rating (as in pounds to pull). the ones i got from home despot were 40 lb, and that is way too much. if you get up under the dash with a good floody light, you can probably spot a body panel that has a convenient hole stamped in it. i used that, but its alignment with the pin on the pedal isn't ideal, which is why the strumming. it grazes another bit of body panel. you can measure the distance from that hole to the pin. the first springs (the HD ones) i got were shorter and stout, and i ended up making a linkage out of some round mild steel rod. the second (current) spring was a little longer, which is good, and i could shorten the linkage quite a bit.
if you go to napa or a hardware store to find a spring, one test of fitness for purpose is that you can hold it at the end and bend it somewhat with one finger. if it's too stiff to do that, it's too stiff for this use case. if it's really bendy and you can easily bend it 90°, that's too soft.
my wife drove the 4R today to work, or i'd have taken a photo of it for you. i can get you one later if you'd like.
here's the first spring i tried (home depot purchase), the one that was too stout.
