salty57 2 #1 Posted April 29, 2011 My 1973 12 8spd Model 1-350 has 1-1/8 axles, did the 5073 transmission come with the 1-1/8 axles or do I have the 5091 transmission? Share this post Link to post Share on other sites
racinfool40 202 #2 Posted April 29, 2011 The 5073 tranny should be a 10 pinion limited slip with 1 1/8 axles the 5091 should be a 8 pinion with 1/8 axles The 5073 brake drum should be close to the axle and the brake drum on the 5091 should be close to the front of the axle.. :thumbs: Share this post Link to post Share on other sites

TT-(Moderator) 1,145 #4 Posted April 30, 2011 The 5073 brake drum should be close to the axle and the brake drum on the 5091 should be close to the front of the axle. Actually, the 5060 and the 5071 (1967/68/69) are the only two (that I can think of) that would have the brake drum mounted to the pinion shaft. (closest to the axle housing) The 5073 has the brake drum mounted on the countershaft: Share this post Link to post Share on other sites
