Doan fergit that the later cars had the motor set back 2"`~ on the K member....as Dion discovered when he put the later K in an early car.

When Dennis swapped driveshafts the 2" difference in wheelbase was negated by the 2" setback in the later car.....or something ........

Ding, ding, ding!!!! We have a winner. Wheelbase is meaningless unless the motor/trans are in the same place.

Have yourself a red ale for that one Sandy.

OK.....fill yer boots.

Do you mean between 72 and 73, the motor was set back 2"? I never knew that. How did they get the trans mounts to work out? Does the later car have the trans mount further back?

"Boot to the Head..."

Don't judge a prize by the package. Sandy did not, in fact, say what to fill your boots with.

This all seems to mean you get some ale delivered in a container that is personalized ..........

And how about the torsion bars? They go in the trans mount cross member. If all torsion bars are the same length, then the LCA's must be further back too. If this happens, then the wheel base is shortened by 2". This is too interconnected to be simple. It wold be interesting to take a tape measure to two of these cars and figure it all out. Sam

The information I have: The engine/tranny is set back 2" in the '74 as compared to the '63. Wheelbase for the 1963 Dodge Dart GT is 111" Wheelbase for the 1974 Plymouth Valiant is 111" My driveshaft will be 2" short according to this. Right? CJ

I don't know. How long is your existing driveshaft from one U-joint center to the other?

54" on the Valiant C-to-C CJ

I have had three cars here recently all with 7 1/4 rear ends. All the original driveshafts are here. The 108" wheelbase '75 Duster and 108" wheelbase '67 Valiant both had 51.5" driveshafts. The 111" wheelbase '72 Dart has a 54 3/8" driveshaft. That's only 1/8" short of the difference in wheelbase between the Dart and Valiants. If the '66 and earlier cars have the engine and transmission farther forward then the driveshaft will have to be longer. In fact this chart shows a '66 Dart driveshaft is 2.25" longer than the '67-'76 unit with the same 904 trans and 7 1/4 rear axle. Looks like you could put an 8 3/4 under the car with your existing driveshaft, but need a 56.6" driveshaft to keep your existing rear end.

I just got back from DusterIdiot's place. He showed me where the two inches comes from when the wheelbase is equal. It's all in the mount. Hey Doc! Did you ever work up one of your instructional posts of using the spool mounts with a flat mount K-Frame? CJ

Ceej and I looked things over since I was fortunate to have a '67 and a '76 at our disposal (and his '74)... The way it looks from the 'late' stand point... the 67-72 uses an 'offset' mount on the engine to move it back 2" in relation to the 'pad/sandwich' on the K-member... the 'spool' mounts use a straight mount that locks in the cradles on the 73-76 K... -D.Idiot "Boot to the Head..."

No you said 'boot' and one of my favorite comedy teams is the Frantics from canada.... of course I wouldn't mind getting one of those beer glasses they had in the movie brewfest... then again midi did show up one night and personally delivered an IPA with my my name on it.... But I digress on a tangent... -D.idiot
