Help with finding pieces

Hey, so I’m new on Reddit in general, but I’ve been really into mega bloks for a while and wanted to build some of the structures from some old sets, for example set 96967 (assault on the high ground) so I’m looking for adequate official Lego substitutes for the bricks that makeup the structure for this set, I have instructions if it helps: submitted by /u/No-Caterpillar306 [link] [comments]
