I've had problems with headlight bulbs burning out quickly when I haven't used dilectric grease on the headlight connectors. I'd recommend cleaning the old dilectric grease off and putting some new stuff on there when you change the bulbs.
It's a similar situation. Neither the 1UZ nor the 1FZ came with a manual transmission in the US. It takes some knowledge of the Toyota parts system to put together all the parts from Toyota (some are probably discontinued). FJ Company makes a bellhousing to mate a H series to the 1FZ. Dellow in...
I don't know who would be the best distributor would be, but all4swap out of Russia makes a piggyback module that allows the UZ ECU to work with a manual transmission.
