Anyone know of kits for the T28E1 or the Israeli 37mm flak halftrack?

Stumbled across these while browsing today and fell in lvoe with them. So anyone know of kits/ resin conversions or easy ways to kitbash or minimal scrachbuilding for these vehicles?

Heres a link to a T28-E1:

Heres the Israeli 37mm flak:

The T28-e1 is way out of my league for scratchbuilding, but the Israeli 37mm version…Start with one of the new DML or old Tamiya ones, and then kitbash the flak 37mm on? I couldn’t find links to the real vehicle though, so I’m not sure how many other differences there are, but I’m up for trying a bit of scratchbuilding. What would you suggest for the 37mm? Thanks, Ian.
