Re: Sum Old Parts -72- 2wd conversion

Hey Jim Trailing arms are not too bad, all the extra's make it worse than it should be. Parking Brake cable, axle saddles and Spring perches need to be different. Shocks I moved the stock mount back a couple inches and it seems to work. I have an extra set of trailing arms and cross member if you decide to go this route...Ed.

Thanks Ed. for the info., i may take you up on the offer, the only part i m having a problem wrapping my head around is the transverse arm. I found a rear end outta a '96 tahoe for 150.00, so all i have to work out is the coil overs. Were there OEM holes in the frame for the cross member, i see you have demension sheet, and did you work off of that

How s the truck running.....

Re: Sum Old Parts -72- 2wd conversion

Spec sheet is a big help, maybe a couple holes line up. Not a simple bolt it right up kind of deal. Blazer Runs very well, needs some weight in the back, and maybe some drop springs to level it out.

Re: Sum Old Parts -72- 2wd conversion

What did you find the easiest way was to install that front crossmember in the correct spot? What did you measure off of?

I might be converting my blazer.

Re: Sum Old Parts -72- 2wd conversion

Some of the bolt holes lined up, took as many measurements as possible off of spec sheet, center of radiator support 21 7/8" to center of 2wd cross member. I used cross member from an 1982. LMK if you need other measurements.....Ed

Re: Sum Old Parts -72- 2wd conversion

Thank you. Any photos of the front crossmember installation you can provide?

The measurement of 21 7/8 is that measuring straight across or somewhat diagonal following the frame line?

Re: Sum Old Parts -72- 2wd conversion

Photos are not a great help on placement...All layout should be done strait and level with the frame, keep in mind wheel base 104" so you have a starting point in the back. Mark the center of the rear axle and measure forward on each side, scribe a line on the frame. Double check across with a square on each end, and diagonally if possible someone here said 105" looks to be better for centering wheels, matter of preference. But may give you more room in the engine placement. I also used 1/2" blocks on top of frame for engine stands.

Re: Sum Old Parts -72- 2wd conversion

Thanks for the help.

I was thinking of getting the frame level. Then use a laser plumb-bob to precisely measure the lengths on the floor transferring them up onto the frame

Moving the front cross member forward, wouldn't that cause issues with other stuff lining up? Or were you talking about the rear?

Re: Sum Old Parts -72- 2wd conversion

Keep as close to 104" is the best bet, Layout on the floor would work well then transfer measurements up. If you do a rear axle flip, it would greatly simplify your build. Rear leaf springs and shocks ready to go
