Has anyone done a conversion like this before? | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Just out of curiosity, why are you wanting to swap frames? Not much, if anything, to be gained by swapping. The '68s already have IFS, and upgrades are very easy to do.

Disc brakes, Handling equiptment, etc. This whole thing is just a thought as the 68 frame is fine. | | | | | Joined: Aug 2007 Posts: 1,859 Grumpy old guy playing with trucks, cars, and boats | | Grumpy old guy playing with trucks, cars, and boats Joined: Aug 2007 Posts: 1,859 | TC, if I remember, there are tubular A-arms for your 68 that are not too bad. A set of Q1 coil overs and a 4-bar setup would be low$ as well. While you are right, it will set you back about $1000 to $1500, it would be better than a stock '91 unless you did the same upgrades.
Disc brakes were available in '71 if I remember right. So you may have parts available.

Out back, the stock '68 suspension will outperform the leaf spring rear handling wise, or as Scott pointed out, a 4 bar can be easily installed.
For the time, effort, and cost to swap the frame, you would be ahead to upgrade the stock frame, and get a better handling and braking truck, plus you'll have a truck that the frame and body align to each other correctly.
