Power Window ID Help Needed

[musclecar fan]

I bought 5 pairs of early GM muscle car power window regulators from an estate years ago. Are there any experts out there that can ID these if I post pictures? Thanks

im no expert..but ive had a sold many sets..many..i can usually ID 68s...69s and 70-72 by pics..

i have a set of each and also a set of 66-7s for comparisons if i cant tell..

early a-body convert is difficult to ID you have to count the teeth on the pinion

theres numbers stamped into the metal regs usually..and those numbers show up in hollanders.

If anyone can ID any of these I'd really appreciate your help. Each pair of pictures is numbered (Set 1, Set 2, Set 3, Set 4, Set 5, Set 6 and Set 7). Thanks

set 4 looks like 70-72 a body front

st 5 looks like 68 only a body and 68-72 elcamino fronts..the short arms because of the vent windows..maybe not sure

set 6 looks like 68-72 a body rear..no such thing as convert only in 68-72 works for both

all the rest are 69 and down, with the double arms..i am looking on my phone..when i get home,i will get on my PC..its hard to tell on the small screen on my phone

theres numbers stamped on the regs..those early ones, you will need those numbers and a hollander interchange...i recognize a few but..a couple are strange to me..
