Which years of TBI units will drop onto my 95 Yukon TBI with no modifications ?
I want to pick up a spare at the auto wreckers to fix up and drop on.
Are there a couple of years that are compatible to a 1995 ?

'93-'95 are identical. '91-'92 are the same except they have a single air cleaner stud instead of the dual for 93-95. '91-'92 has a connector on the linkage for the TH700R4's TV cable. Earlier models have different style throttle position sensors. The injectors are rated different for each particular cubic inch engine they came on.
