alex's72fgmc Posted February 28, 2007 Posted February 28, 2007 is the tranny the original one "short output shaft cover type" or is it a replacement with a longer out put shaft cover? also what is the measurement of your drive shaft from center of u joint holes to center of u joint holes Alex i will measure mine tonight and let you know my measurement.

Guest Posted February 28, 2007 Posted February 28, 2007 i couldnt tell u if it was new or not i think it might be because i thought most montes came with 350s but that dosent mean anyything im not sure ive found a place to give me an aluminum driveshaft so maybe they might be able to fix it.... and i was curious have u ever heard of that kinda proble before Quote
Arizona Monte Posted February 28, 2007 Posted February 28, 2007 If you need measurements for drivshaft length I have one for a 350/350 car, out and can get them for you. That way you would know if lenght is possibly part of your problem Quote
HarrisQ Posted March 1, 2007 Posted March 1, 2007 I just had a new drive shaft built for my 72 that has a 402 BB and a TH350 and it is 56 1/2 inches from center to center. Quote
buster Posted March 1, 2007 Posted March 1, 2007 Had the same problem years ago on a Monte i bought. After putting a drive-shaft in out of a different Monte the problem still wasn't cured (to short). After looking closer I found someone had replaced the motor mounts with the later 70's /80's style and hadn't pushed the motor back far enough before welding (YAH WELDING) the mounts to the cross-member. Since the 327 was discontinued in 1969 and Monte's wern't available with them, we no the motor has been changed in your car so it is possible the mounts may have been moved or replaced. Just a possible cause in case the driveshaft length is correct of-course terry Quote
alex's72fgmc Posted March 2, 2007 Posted March 2, 2007 There are 2 types of th350s long tail shaft and short shaft "the long tail is for trucks" this is why i asked as the wrong type of tranny put in or wrong drive shaft lenth can cause this. alex Quote

kc8oye Posted March 2, 2007 Posted March 2, 2007 Techniclly.. there are 4 4x4, short, medium and long. 4x4 is basicly just a plate bolted to the back of the trans as the speedo unit is in the transfer case. Quote
