Competely different car under the skin.....3b is almost competely aluminum and very similar to the T160 series Can Am cars...whereas, the Mk3 has much more steel and more in common with the earlier Lola Mk2's ....
the 3"B" name was used to bypass homologation issues back in the 60's...it should really have been named as a new car....this is the brief synopsis as I understand it.
