Back Yard engineering , DIY

Hey All,  
   Just thought of a new post in the last few days and was wanting to get it started to see where it goes.
   Almost everyone has a story of how something was fixed with only duct tape and JB weld(or baling wire)  Shocked
  I was wanting to get some Ideas of how AMC'ers get around some of their obstacles with good ole backyard engineering.
    Lord knows I have many homemade parts, and fabrications on my ole yeller car.  
   I'd like to know what parts were made and how, staying away from the high buck one off billet trick pieces. Just stuff that could be made by the average Joe with a little incentive and even less money!
 Now lets see what ya got! Grin
 
           This should be fun-------Lonnie

Thought I'd start it off with a partial list of homade parts that are on my car.
 If anyone is interested in how anything was made just post a question..
here goes:
wooden carb spacer,  
led third brake light,  
 brackets to mount a 120 amp nippondenso alternator from a 93 dodge caravan
power steering cooler from srt4 neon
factory delco distributor reworked with Mopar reluctor and pickup/mopar orange ECU
  HD front window guides made from 3/8 thick plastic cutting board from the kitchen
home built modified crossmember and 8 qt oilpan with trap doors and windage screen ( only 1/2" lower than stock)
and yes the dreaded mopar converter with the ring gear removed
I guess it is a wonder it will even pull out of its own tracks with all of this jury rigging!  
  Have fun---Lonnie

I'll bite, I'd be interested in what you did to your crossmember and modified stock oil pan. Any pics?
As far as homemade goes on my amx I put together some weld in subframe connectors out of 2x3x3/16'' tubing. Also some lowering blocks out of solid aluminum(I know billet but easily cut with band saw and drill press. All made in the garage.

For the cross member I first raised the car up and measured to find out how far forward I could move the center of the Xmember and still clear the steering.  
Then I took an old xmember and tack welded it to a steel plate on both ends and braceed it enough to hold it steady while I cut the center out. Then I capped the ends with 3/8 thick mild steel plate and added a 2x2 .250 wall square tube to reconnect the two ends.  
  Then I mounted the Xmember on and old 360 block with a cutout oil pan and built the pan to fit and miss the new crossmember!
 I made a pattern for the pan out of cardboard and transferred it to sheet steel and just welded it all up.
  Took a little time but the results were great! holds 8qts and the oil level is 1" lower than stock(farther from the crank)I had to cut the dipstick tube off 1" to get the level correct on the stick.

I added a lower radiator support made from aluminum channel. The support is heavy duty enough that it also acts as an additional front crossmember. Also made 2.5" lowering blocks from square steel tube. Used a long Allen bolt thru the block and center of the spring. The head of the Allen bolt also acts as the locater for the axle. Not being a welder kind of limits my creativity.

The trans pan is from Derale, it does have cooling tubes in it. they are readily available and are fairly cheap.Summit carries them. The one for a 727 is $81.95
part # DER-14110 when I bought mine it was about $60 but that has been a few years..

Well, I was hurting for rear tail lenses with the chrome framing over it for the 72.. I wanted something that was as close to show quality as I could get and not pay the STUPID $1000 + price tags for new lenses and housing.... so I started searching the net and found some 1/8 chrome stripping for about 20 bucks... said what the hell I will give it a try, also went and purchased a plastic surface revitalizing kit for about 30 bucks.... and let the elbow grease fly!! Think it came out very good in my opinion... here are some pics at the start and finished product...

Schweet! Now I know how how to resurrect some otherwise clean '72 lenses that are exactly like in the first pic you provided! Awesome! When I can borrow a camera with a zoom I'll post my "pcv bypass" modification.

Lonnie, nice work on the crossmember and oil pan  Smiley I'm sure alot of thought went into that and it shows. JP, those lenses do look good, I lucked out with mine all the chrome is there and in good shape. Keep the ideas coming it's all good food for thought!

This is my new favorite thread Wink
I work on computers for my day job and I enjoy nothing better than a good back yard engineering project.
I posted this before, but here it is again.
I am installing an adjustable panhard bar on my Javelin. I started with a kit for a mustang, so far I only have the axle portion complete.  
I cut the front off a stock spring plate to get the shock mount. I mated that to the mustang spring plate that has the panhard mounting.

 
I also boxed in my lower control arms using the pictures from the old TA cars' lowers.

 
The next thing I want to do is make a back yard version of a cold air intake starting with a stock air cleaner assembly.
NEXT PERSON PLEASE! Cheesy
