Hmm , I have the Asiatam hull , it comes with torsion bar suspension a la Tamiya + track tensioners . The Mato one is basically the HL - but made of cast alloy . They don't have much in common with each other . Trying to cross pollinate parts can mean reworking them to fit .
Mato - same as HL , but in metal . ( An all metal Tiger 1 is in the pipeline

)
Asiatam - SIMILAR upgrades to Mato , but often has better detail i.e. working hinges etc. - possible fit issues .
You can see in the vendors section what's available , by all means ask questions - then decide .
