Hello Michael,
Beginning in 1966, all the later 150's and 152's had the same dimension cabins.
With that said. We just very recently had a spirited discussion concerning the differences, pros and cons, between the 150 and 152. You will find that discussion
Here. Enjoy!!

You will also find a complete listing of year by year changes at the main club site under this title:
