Monza vs Vega 'frame' comparison

Postby potshot23 » Wed Oct 14, 2015 1:14 pm

I have a 77 Monza, and was wondering if the unibody frame is exactly the same as a 71 Vega??

The later Vegas and all Monzas have a larger trans tunnel to accommodate the torque arm, plus the panhard bar mount in the rear. The lower control arms are however the same whether the car is 3-link or 4. The front section of the unibody would be the same.
The "fleet"-
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
72 Vega HB Drag Car -383/'Glide/9"(9.35@146.19)(5.94@117.28 1/8th)
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
03 Silverado 2WD (work truck/parts hauler)
04 Silverado 2WD (retired)
06 Haulin' 20ft enclosed car transporter
93 Suburban- 350/4L60(retired)
00 Saturn SW2- wife's car
01 Saturn SC2- younger son's project
00 Saturn SL2- daughter's car
98 Saturn SW2- spare
and 3 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....

I do recall when the Monza was being introduced that they made mention of some additional strengthening to accommodate the V8. There was reference to some additional sheetmetal patches to help make the unibody a little stronger. I can't say exactly what or where these were but there may be some slight differences.
