hi,was looking at the tr7 box as i thought it would be a reasonable swop,thought i could use the clutch plate and housing, one off a 1850 and other off sprint as they are same part numbers that fit the early tr7 box and use the early tr7 prop flange onto the dolly prop, did not know the bell housing was so much bigger to foul the steering! that one i cannot easily get around... as my daily drive is 50 mile round trip, all at reasonable speed, no crawling threw towns as i live in norfolk, i thought the five speed would be best option for reliable,economical runs. though i suppose a sprint axle would reduce the revs to a reasonable level. regards jim

So long as you're not doing burnouts all over the place the original box should be OK - you might as well wait until it breaks before changing it...
