<div dir="ltr"><div>Early Spridgets have 4.22 diff ratio. Later models have 3.9 and really late Midgets have 3.77. 3.9 and 3.7 are highly sought after for the very reason you mentioned. I've seen 3.9 and 3.7 diff chunks go for big bucks on ebay. <br><br></div>From <a href="http://mgexp.com">mgexp.com</a>:<br>"'78 ~ '80 Midgets came with 3.77 ratio (8/'77, from GAN6-200001), better
for highway use than the 3.9 used from 12/'68 ~ '77 (but the 3.77s are
rare, so more expensive). "58 ~ '68 (948 and 1098cc) used 4.22. The
ratio is stamped on the upper RH surface of the diff housing."<br><br>

Last year I bought a 60 bugeye that was modiifed by the previous owner to have a 998 cc motor, rib case and a stock bugeye rear. It has more trouble with highway speeds. Could I swap out the stock bugeye rear for a late model midgets? Would that improve performance?</div><div>Thanks</div><span class="HOEnZb"><font color="#888888"><div>Ryan</div></font></span></div></div><br>------------------------<br>
