sounds like it's above my expertise. Considering how the Prius Electric steering is a simple upgrade for older cars, that the electric brake boosters, like the UZJ100 and such would gain some traction as a swap or upgrade.
What's required to put an electric brake booster from an 01-02 3rd gen into an earlier third gen?
I've tried searching so if you know of threads discussing this please link them instead of telling me to search.
keep landcruisers in mind too. bigger and more powerful for towing. but might be scarce in ontario. there was a 100 series for like $15k on kijiji recently
