They don't bolt up but ive herd you can get a custom bellhousing, but there really rare, the company didn't make them for very long. Ive got a k5 behind the 4k & a t5 sprinter box behind the 4AGE. I don't think the Sierra box would last long behind the 4age, probably go bang...loudly. I just pulled the K5 down to put some new seals & bearings in him and found the hardening on the cluster & shaft is stuffed. Its an older k5 with only the reverse light switch in it. Ive got a k5 from a ke70 for it but the shifter is in a different spot and the mounts are different. look like ill be making a new crossmember again. The newer one might be stonger, I don't know yet. I'm told its the same length and will bolt up to the 4k the same apart from the mounts.
not sure if there is any. aren't they an east west engine? the sierra has an independent transfer case, its not attached to the gear box. there is a short drive shaft (called a jack shaft) from the gear box to the transfer case. the sierra has a live axle in the front, lick a rear diff but with swivel hubs with cv's inside them . I don't know, but Id imagine the tercel has an independent front end?
Hope I answered your questions at least a little bit, or maybe I just confused you more. I don't know much about tercel in case you were wondering.
Me & the boys have a carnage points system :hmm: were you earn points for trail carnage/rockrash when its done by accident while attempting the near impossible. As he old sayen goes, “rollen and beers†:)
