I have a 440-6 pack k-member it has a coin.Trying to find out more info on it.Has a round coin (90) and the only stamped #'s I found are 1 0 1 just like that in the middle front next to coin?

GG's book has a list of coin numbers for the K frames.

I looked in my book no #'s I might have just an old book?

I bought a K-frame from a parts guy about 10 years ago for my 71 Challenger project and it also has the coin and I think it has the same numbers??? I never gave much thought as to why it had the coin tack welded on???? TBF

#90 shows as a 1970 b body 318-383 in the white book. #74 is the number for a 440 with a skid plate for e body, #77 for 440 b body.

***My K-member has a sway bar and a skid plate***.Very sure there original, pretty banged up.I Never seen a 318 or 383 k-member with a skid plate and swaybar unless it was a cop car or special order?Car was last on the road in 1984.My car is a 1968 not a 1970 though.I will sell this k-member once I figure out what it is.Usually a skid plate was for the 6qt pan motors because they sit lower.1970-72 440hp or 4406pak or hemi.
