I believe the T-4,T-5 and SR-4 all have the same bellhousing. To double check ,go to Novack Adapters.com in the knowledge section under transmissions. This is a great reference site for tranny swaps.  

THE TRANSMISSION MOST FOUND IN THAT YEAR SCRAMBLER IS A T-176.  IT’S A PRETTY GOOD 4-SPEED.  IT HAS A DIFFERENT BOLT PATTERN THAN THE T4/5 TRANSMISSIONS.  THE T5 WILL MOVE YOUR SHIFTER A LITTLE FURTHER TO THE REAR AND YOU HAVE TO MODIFY THE COVER SOME.  I SWAPPED MY T-176 FOR A T5 THIS SPRING.  IF YOU HAVE THE T-176 YOUR AXLE GEARS ARE PROBABLY IN THE AREA OF 2.70 SOMTHING.  THE OVER DRIVE ON THE HIGHWAY TENDS TO LUG ON THE HILLS UNLESS YOUR SPEED IS UP PAST 65 MPH.   I ALSO, A COUPLE MONTHS AGO, SWAPPED IN DANA 44 REAR AXLE AND MATCHING 30 FRONT AXLE, THAT HAS 3.31 GEARS. THIS WORKS WELL ON THE HIGHWAY, PARTICULARLY WHERE YOU NEED TO HEED THE POSTED SPEED.  IT ACTUALLY GAVE ME A COUPLE MPG’S IN TOWN AREAS AND ON THE TRAIL BECAUSE YOU CAN GET TO YOUR RPMS QUICKER WITHOUT STEPPING INTO THE GAS TANK AS MUCH.  IT GAVE ME ABOUT 6-8 MPG’S ON THE HIGHWAY. AT TODAY’S PRICES THAT’S GOOD.
